Good morning all, I have a question

[gatorschevy]

I own a few older quads mix of kinds a couple of  Yamahas, a Honda, can-am  a Kawasaki, they are older quads but in good shape the question of the day is....... what's the best way to polish up the plastic?

 I have found that Dollar General mold remover is good to get the black stuff off the plastic works good, but was wondering how you polish up the plastics on yours.

[catman977]

I have two 1988 Yamaha Terra Pro's, and found if you wet sand the Plastic with 220 grit sandpaper, then blow it dry with a compressor.  Use Denatured Alcohol  to remove any oil from your skin, then it is ready for a Bonding primer, which is sold by Sherman Williams.

it's in a Brown label can and around $12. , it sprays on white.  I then dry sanded with 320 to smooth out the Primer, and then again use Denatured Alcohol.  You are now ready to paint any color you like, as long as you use Fusion, or any that says bonds to plastic.

I have found that this Bonding Primer is the best and will not peal as others do.  Good Luck.

If the plastics are really bad sanding with primer and paint is the only option as Catman said. I paint plastics as a last resort. If its heavily oxidized i scrape all the oxidation off lightly with a razor blade at 90 degree angle to the plastic, I say lightly you don't want to gouge the plastic. Then I go over it with 000 steel wool, next wet sand with 220 until you get a uniform smooth finish. Continue wet sanding with finer grit as you go 400, 600, 800, 1000 , 1500 I usually don't go higher than that. Then use a good plastic polish. Its not as good as new but its a good 5 footer.

Just curious, if the color coat is bonding to the primer why use the fusion? And how does the paint hold up over time? I've not seen anybody say how their paint jobs looked after a year.

[Gwbarm]

From what I get, you are using fusion, a krypton paint for plastic, over the sherwin Williams bonding primer. The question is why use bonding primer if fusion is for plastic.

[Jim Denton]

Thanks for the clarification. I'd really like an answer to the second question. 

[Jim Denton]

Or just enamel paint over the primer?

[Jim Denton]

Well happy Saturday. It's a gorgeous sunny °5 kinda morning.

I got one in my shop right now that has rhino lined grill on it. I've seen a whole quad done before and it holds up really good and looks badass.  you can even use the roll on stuff. and now it comes in all kinds of crazy colors

[Jim Denton]

Now there's an idea. When I get to the King Quad I'll be doing a lot of plastic welding so shiny is way out of the park.

Would you ask the owner what product was used please? Dunh I reread your post and answered my own Question. Rhino liner is some serious stuff.

The plastic on one of my ATVs was scratched and unsightly. I lightly sanded it and then refinished it with a colored spray-on bed liner material. It looks great and is very durable, especially when riding off-road

What brand? I'm leaning towards POR15. Not worried about pretty, so much as uniform. 

[406offroad]

I used Raptor 2K bed liner aerosol by Upol,

I clean with brake kleen on a rag. after fumes are gone i hit it with a heat gun. go light and keep moving brings back some shine.

5 footer lol, is that like 20/20 vision? Looks good from 20' away as long you don't stare at it for more than 20 seconds 

[wiktoriatopajew]

go to youtube and found channel " Plastic polish " 

[Gwbarm]

Thanks for the info , I will take a look, im always interested in how others restore plastics.

[Gwbarm]

Thats my vision but it hasn't been 20/20 in many years, so for 20/20 maybe a 10 footer.

[406offroad]

I had an ATV that had a lot of scratches, so I refinished it with a spay-on colored bedliner. The color matched the plastic perfectly and it's extremely durable.

[Gwbarm]

I have not tried that, been tempted several times, I thought it might be a rough surface to keep clean, glad to know it works.

[kyote]

Burn it with a torch lightly or SL1 is my go to.

[Gwbarm]

I tried doing that it didnt work out so good for me. I think i probably didnt get even heat on the big area and it was not uniform, kind of splotchy. I have been trying to figure out how to get a large even heat  area hot enough, bigger than a torch or heat gun.

Watched a video the other day on polishing plastic he used an aluminum polishing stick with high speed buffing wheel on a grinder that could be set at 3000 rpm. Haven't tried it myself but he fixed all the plastic on an old quad to like new condition and didn't take long even did a windshield to a side x side. 

[406offroad]

I had an ATV that was scratched and faded so I sanded and refinished with a colored spray-on bedliner from TPC Global. It looked great and was very durable.

[kp3004x4]

Some bed liners might just work but I'd make sure about what adhesive that is in it doesn't melt the plastic after awhile.good idea
