Fading plastic trim


Brad & Jacolyn

Recommended Posts

Good Morning,

    Some of the black plastic trim below the sides of the head lights on the Volvo have faded to almost white and I was wondering if these parts could be painted with black paint for plastic parts. Would it even stick to these parts? Would I have to do anything special to prep them and should I use clear coat over any paint. Is there a special paint I should use? Thank you for your suggestions.

Brad

I used the heat gun trick on motorcycle body panels.  It looked great for a month or two, until the plastic dried out again.  Just say'n.......

All it costs is a bit of time. Just sayin. Jeep parts must have more oil in them, I do our fender flares about every 2 years, to get rid of the blotchiness.

Thanks for the suggestion guys.

I tried the heat gun yesterday and it had no effect at all. The panels were to hot to touch and I was afraid to heat them any more. Guess I'm back to the plastic paint question. Would it stick to these panels?

I've used a product named "Back to Black" and it works for a few months, but then fades. I have often thought about a paint, but never tried one.

I used the "Back to Black" by Mothers purchased at an O'Reilly's auto parts store for my 10 year old jeep fenders.
The fenders are not the painted type, they're some kind of plastic, maybe polyethylene?
The fenders were noticeably gray, not white as in your description.
The product works and takes some elbow grease.  The application rag turns grayish - indicating that something is coming off the fender.  I suspect that the product might actually be dissolving a bit of the surface material in order to restore the black. 
Maguire's also offers a similar product (but on sale and out of stock when I purchased).
Mother's also offers a stronger Back to Black version according to the product literature.

Using the heat treatment method with some kind of UV protectant afterwards would probably be the best way to go about. I don’t know if  it would last much longer than Back to Black though. I intend to try it, but haven’t yet

Brad, yes you can paint them. They make a plastic paint...I think it allows more flex than regular. When the shop where I live painted mine I thought it was something they added to the paint. 

Edit...and here is a rattle can made for plastic

You can use a urethane automotive paint but to make sure it stays on, use an adhesion promoter first. After that, try a base coat of black followed by a catalyzed, semi gloss top coat.

The top coat can be bought in a can and has a "button" on the bottom that is pushed in to release the hardener into the paint.

If you take your time and follow the instructions, you shouldn't have any more problems from your plastic trim.

The Eastwood paint is supposed to be top of the line. Next would be SEM, according to my friend that owns a body shop.

Sem is really good stuff and they carry the promoter.  Make sure to remove all oils and waxes.  When spraying color do light coats.  Lightly scotch bright plastic prior to paint then clean. 

Sem 38343 Vinyl Prep, my can is half full.
