How can I remove paint from plastics?

Or it will soften the plastic

Which one will soften it?

All plastics on the bike were painted with automotive primer and paint. Only thing they forgot was the flex agent. So every compound curve or flexible part caused the paint to crack and chip off.

How can i get rid of the paint without harming the plastic?

I was thinking of using paint stripper and scraping it off before it chewed into the plastic.

Someone was recommending using graffiti remover as well.


Any ideas?

I have used silicon carbide wet\dry paper to strip a plastic fender for a bike.
You basically treat the process like buffing cases. Start with the coarsest needed to break the surface of the paint and start reducing coarseness.

2000 grit is more of a polish than an abrasive.

I painted said fender using flexible primer and used a base-coat\ clear-coat pairing.

It worked really well considering it was good old Canadian Tire brands from start to finish. ( HA to finish is funny yes? )

Both but the acetone might a little quicker.

You could use it to get the goo off quickly, just don't let it sit there.

lol, I liked the old stuff they had. Now its nothing but problems with the duplicolor. But it looks like that brand is coming off the shelf. All the shelves are empty around here.

I'm debating on doing it myself or getting someone else to do it now. I just don't have the place to do the quality of job I want to do. I was quoted 600 but a paint shop here before I did most of the hard work. Going to do as much as I can and then see what they will do it for. Who knows Might be worth getting it done maybe not.

I have the plastics stripped. Used an orbital sander and 100 grit. Found lots of cracks to fix and fill on the way. 5 minute epoxy? not a good crack fixer :-k

Not surprised really after everything I've seen.

The only thing left to strip is the tank and I was thinking of doing that part with airplane stripper.

I'm not sure what the paint color will be but I'm going between the original color with a bit of metal flake or the rebull blue.

Some more inspiration for you.

Regardless of what paint you use prep is the key.

A quick cell phone picture of 1 side panel and rear fender from my XL project after clear coat. Not buffed yet.

Epoxy primer and Duplicolor red metal flake 5 coats / Spraymax 2k gloss clear 6/7 coats total cost for paint, stripper and sand paper around $120.00. Time about 10 hours.

Not really. If you immerse it for awhile it might, but just using it to remove the glue adhesive shouldn't cause any problems. I've used them both tons of times to get old glue off of side covers and tail sections. Acetone's a bit more expensive, but really cleans things well with no leftover residue. Lacquer thinner's a bit more versatile for painting purposes, though.

What would you recommend using to remove the vinyl adhesive off of the plastics? I used a blow dryer to heat up the vinyl and peeled it off, but it left a layer of adhesive on the side covers. I've tried goo gone, scratch pads, and sand paper. The sand paper works to an extent, but I'm worried about sanding down too far. Does anyone know of any strong adhesive remover that won't eat the plastic?

Thanks

lighter fluid (for Zippo cigarettes lighters) takes gummy adhesives off. Never seen it harm the plastics .

So all in all does this thing about Steve Murphy and Cindy Day have you perplexed?

Awesome. I'm just in Enfield

I found that the only thing that worked to get the adhesive was to go over it with a hand sander with 100 grit, then use elbow grease and 250 grit after that. but the job is done and they are ready to paint!

Well tonight I've tried plastic welding for the first time

Got the cracks filled but still have to sand it smooth and fill it what ever I missed.

Have to say that there is an art to it!
