Oxidized or faded plastic body parts

Recommended Posts

I recently read an article about restoring or at least improving the looks of faded and discolored plastic body parts. In the article it suggested using a 50/50 mixture of boiled linseed oil and paint thinner. You mix it up and apply it with a brush or rag to rub it in and remove the oxidation. I curious to find out if anyone has had experience with doing this and what was their short/long term results of doing so. I would hate to try it and find out that a few weeks/months down the road my plastic body parts self destruct.

I can honestly say I've tried it all! Linseed oil, water sanding with 2000 grit paper and trying to buff it out, heating with a heat gun (worked the best) but nothing will bring them back! I use armor all to give them a decent look but nothing is going to ever bring them back to the way they were.

Thanks, thats good to know. I decided to try and test the boiled linseed and paint thinner 50::50 mix on a small test area and was impressed with the results. It didn't leave it looking new but it did make it look a lot better. The best part was that is very easy to apply and with little effort. I have used armor all in the past but after a few hours the chalky white oxidation starts to show through again. The test area with the 50::50 mix was applied about 4 weeks ago and it still looks much better than before. I just have not done all of the pannels because I was concerned about the long term effect degrading the plastic. So far I have to give it a thumbs up.

I agree. It does look good but mine did not hold up that long as well as being a magnet for dust which results in washing the atv and that washes off the oil. 
its great when ur selling an atv !

I'm going to have to try that. @Frank Angerano  did you use propane or other torch/heat. Or a heat gun? I saw this video where they are using a torch:

 

Here's a guy using rubbing compound...

I used all methods, flame, heat, buffing etc. None of which held up very well. 
I did however water send  and send to a auto body shop where they added a flex agent into the paint and sprayed them and the finished product was insane.

My buddy got some Rust Check over spray on some faded blue Polaris Magnum plastics and when he wiped it off it looked great so he did the rest of the quad. It's been months and it still looks like new.

Cheap enough to be worth a try on purpose.

@Randel1 the best ratio that’s I’ve seen that’s works the best is a 80-20 mix of the Materials you noted. 20% boiled oil is optimal. 
 

but try on a small area as it will take multiple tries to rid the surface of the oxidation.  

good luck

So ive been messing around with faded plastics for a while and I've even sent them out to a body shop for paint since the person at the body shop added a flex agent to the paint.  
I thought to myself why cant i just put a flexible clear coat on them? 
So i decided to give the water sand thing one more try with 1200 grit and it took all the surface dirt and faded white residue away.  Thin i  hit them with a flexible oil based clear coat spray can that i had my local place order for me after asking her to look for something in that ballpark.  

I tried a small spot first and then tried to remove it with gas and a few other things including a light psi pressure wash.  The results were good enough to try half the rear plastic.  I think it worked out great. Im going to do all of them and see how they hold up since the atv is going to someone i know and can keep me up to date.  
The pics are not in any order except for the very last one. Thats finished product of one side of the rear plastic and you can clearly see the difference. In person it looks and feels great and seems durable.

So i got what i wanted to get done and a little more.  The clear coat works great and it's definitely flexible. However  I'm hell bent on and close to having a process to restore plastics like new without any paint or clear coat or chemicals.  Gotta wrap this one up and get it gone asap but I'm going to  get me some old plastics (Where not sure)  and going to have at it.  I plan on recording the process and share. 
Its going to happen this year !

Heating works really well if you get it just to where the surface is shining and then dash it with cold water.  Auto restorers have been doing it for decades on interior trim.  If you don't flash cool the plastic though, it just goes back to oxidized looking.  I wonder if the ATV plastic leeching a bit of oil over time will hurt the clear?  Looks good though.  Can you get the flexible clear you used in a satin?

I haven't looked for it in satin but i will definitely ask. The funny thing here is i tried a small area thinking i could wipe it down with gas and start fresh! Nope! It was not coming off so i had to water sand it. It made me definitely feel better about its durability.

I hope you find the magic bullet. So many we run across need the plastics freshened up but I haven't seen the great option yet.

      Hello guys! New to the forum, and fairly new to ATVs. I've driven them, but never owned one. Now I do own one. Just picked it up today. It's a 1999 Yamaha Big Bear 350. It's been through some stuff. The guy I got it from told me the previous owner removed the front diff because he didn't want to replace the half shaft. So it's 2wd, even though it's supposed to be 4x4. Lovely. I can deal with that for now.
       
      More importantly, I need to get it running. The carb needs to be rebuilt. The guy I got it from said he sprayed it all out and it still didn't work. I'm concerned he might have damaged it or not put all the parts back. I was looking at a replacement carb, and the OEM parts is $600. I'd rather not spend $600 if there are any other options. I have seen carbs on Amazon and eBay that are in the $40 - $100 range that say they fit. Anyone have experience with these? I'm going to get a rebuild kit for the current carb just to make sure that won't fix it.
       
      Thats the first thing with it. Secondly, it was completely rewired. I need to find a original wiring diagram so I can put it back how it was, with a key and all. Currently it's wired with just a rocker switch. Any sources for a service manual that would include wiring diagrams?
       
      Thirdly, is the Big Bear 350 a good atv? I picked it up for $700. It does start and run when you spray starting fluid into the air intake, so I am not concerned about the engine being bad. I plan to use it for the farm, running around and carrying things with it like minerals and feed and such. Not really for mudding and things like that. How good is the 99 350?
       
      I am certain I will have more questions as I examine it more, but that's all for now. Thanks in advance for the assistance!

      Just a couple of things since i get various atvs. 
      They always need seat cover and always need oil and other minor items.
      My question is Do you buy any specific motor oil for them, i heard you must get atv oil or will mess up the clutch.
      Not sure if correct but didnt want to find out hard way. Is there a cheaper oil or can you use regular motor oil?
       
      Next they always need a new seat cover, any good places to buy bulk or cheap vinyl to re do the seats with out spending
      30-50 dollars on a specific cover?
       
      whats you go to places for parts, i use amazon, ebay  any others that offer a good deal? 
      that goes for hard parts or just cables and or clips, wiring, bolts etc no wrong answer here. 
      always looking for new ways to find parts for the older atvs. TIA Az

      Friends, being the owner of a far from new ATV, I often come across a search for various owner's manuals, service guides, parts manuals, etc. It is not easy to find suitable documents for every quad. Therefore, I present to your attention a website that contains various instructions for ATVs from well-known manufacturers: https://www.ATVownersmanual.com
      Currently only 3 manufacturers are represented here: Can-Am, Polaris, Yamaha - and only about 1200 instructions for various models. Little later other brands and missing instructions will be added.
      What will be convenient for you: all documents are in PDF format. If necessary, you can download them to your computer and use offline. The documents are structured by brand, year and model. There is no advertising (yet).
      I am happy to hear criticism and recommendations. If you have missing or rare instructions, send them to PM or to the website's email: info [...at...] atvownersmanual [...dot...] com.

      Does anyone make aftermarket engine parts for the Suzuki Quadsport LT-Z50?
      Pistons, Valves, etc...?
      I have found rings and complete gasket sets.... I need an oversize piston kit and valves..
      One company is selling a piston, but upon further inspection it is an LT50 piston that they are saying is for the 2006 Suzuki Quadsport LT-Z50. Yet the LT50 Piston is not interchangeable with the LT-Z50 according to the pistons listed by Suzuki.
      Any help would be appreciated
