What can I do to fix these spots?

i recently bought a used camper shell. It’s great, except for three patches of what looks like oxidization. The plastic film keeps peeling.

I put a coat of Wolfgang paint sealant on, but it doesn’t seem to stop the film from peeling

What can I do besides having the whole shell repainted?

I want to paint just the patches the same color with some Duplicolor from Autozone, following this process maybe? - https://www.youtube.com/watch?v=Hj9VqSnT-bs

 

The only way to stop peeling is to sand it down. If there's air under the paint, it will just keep coming up.

IMO just sand it all, mask it off, and spray it a contrasting color or black texture coat.

There is no magic. You’re pretty much looking at touch up or a repaint.

 

Anything you do to try and fix that one spot will make it stand out compared to the rest of the paint. It will look better than it does now for sure, but nothing will make it look as good as it was before unless you repaint the whole thing.

 

Or ignore it till the truck's paint matches and ignore both.

 

This is like the sides of my bed. The clear coat is pealing off because of where I sanded it down for my bedliner. It took several years but the clear is finally chipping off.

It all depends on how much money you want to spend. If that is $0, then mask off an area larger than the spots, and it down with some 1000 grit until all the chipping is gone, then give it a couple white coats with some krylon. Since it's white, it's not likely to stand out too bad. Then, take the masking off and give it some coats of clear.

 

It's silver, I'm thinking duplicolor instead of krylon... paint first then clear coat or just clear coat?

 

I'm no paint expert, but you'll likely take off some of the paint along with getting rid of the clear, so I'd throw some color on it too. The duplicolor likely won't 100% match if it's faded a little bit, but it'll look better than "primer grey" lol...

For my bedsides I just sanded (1000 grit) and clear cloated. I actually didn't do a good job as it's pealing again. I actually don't care all that much about it (trail truck) but I'd like to keep it from pealing. Even after just sanding, you could definitely see the "new" paint vs. the old paint - it was faded, so sanding the clear coat off made that more apparent. My truck is red, though...

It all depends on how much you care. Paint is 99% prep work.

 

the vid is helpful. just a few tips,
1) quality paint and clear coat. duplicolor is fine, the clear is whats important, id do X3 coats.
2) climate control. garage with ventilation is fine. high heat and humidity are bad.
3) practice on an ole piece of sheet metal. dont rush, steady and keep a wet edge.
i have 20 years of spray'n cabinets and furniture with poly, lacquer, paint, 2 part, etc... like anything else having the right tools and quality products is key.

btw my truck is doing the same. ill be paint'n my taco soon, low gloss single stage army green. good luck!
