Restoring Black Plastic Trim on the Rear Bumper
 

My bumper trim is starting to look white on the exhaust shrouds. I am assuming this is a result of the heat from the exhaust drying out the shrouds. Anyways, I am looking for a product to make them look like new. I have tried Aerospace 303, which works great except on the shrouds, Mother's back to black, and will soon be trying Klasse plastic treatment. I am looking for something that I don't have to apply every week I wash the car because it is time consuming. Will Forever Black trim dye work well on our bumper? I also heard that Black Wow isn't very good. If none of these will really work, would replacing the shrouds be a near perfect match to the rest of the bumper? Any advice would be greatly appreciated. Thanks.

Back to Black. I know you've used it before, but it really just takes like 5mins to apply and forget.

Mine are doing the same thing....I've just accepted the fact that if I want to have aftermarket exhaust, they are not going to be perfect....

I guess I could extend the tips...

303 areospace..

search google or here..

really good stuff..

beers :beer:

:uhh:

wow,,

got you.

if that product does not hold up... you have issues...

maybe replace the shrouds...

I second back to black. It also helps to work it in with some love, in the shade when the surface is cool.

Now if its from exhaust heat its may not be very repairable, maybe some spiffy chrome exhaust finishers, or some new plastic ones as suggested.

That's it. I third that. Now that the election is over worth. Get back to work.

you should get them sanded smooth and painted.

Id go with the mother back to black too.

Thanks guys. Especially you Alucard. That is exactly what I was looking for.

Im in the same boat, mine are starting to look shabby.

no problem guys... glad to help :)

i actually use a tire gel spray thats meant to make the tires look all black and shiny. Well i tried in on the back plastic trim and it worked wonders. Since its a gel and more oil based it really soaks and smooths on the look and mine is so shiny it almost has a gloss black look to it which looks great against my sunlight silver 8 :)

+1 same thing i do on my SS

i just wish my plastic was painted BB

how about those chrome shrouds that are an OEM option?


then paint them black or soemthing

Same here. When they start to look like they are melting I'll change them out.

MM (Jeff) has them they just burn after time. Wast of moneyz + you cant see them if you have 3" exhaust tips

Haven't really noticed much whitening between washes since I started to use Turtle Wax ICE on my black bits. The shrouds come out looking deep black but not shiny and they stay that why for at least 8 months. It also helps with the water spotting issue on the lips below the fake grills.

I've used ICE with both the stock and my Greddy and all was good. Maybe a combination of Back to Black and ICE would be a good solution. One makes it black the other protects it.

i used 99% alcohol and it never came back, i tryed 70% - 80% and that didnt work, try 99%, its really from the waxs and cleaners that make it like that, you have to strip it off

Meguiars NXT has a purple spray bottle that works REALLY well for black parts. Apply a small amount on a cloth or applicator pad and you should be fine.

I'd suggest that you don't have hot tips during the process....

Where do you get 99% Alcohol? Is this household stuff?

my job, i work for toshiba, and it cant have any water in it for logic boards and other electronics, its really great stuff, i clean rollers that turn white and it gets it black, im sure you can find it on ebay, i dunno

Am I the only one who uses black magic? lol

no, your the only one who posted cause most people just agreed...

peanut butter! i know it sounds redic, but rub it on, wipe it off, and your all set! black as new!

^you gotta be bullshittin, im gonna have rats following my car at 60mphs

lol, can anyone verify this?

take pics

well ive heard that you can clean up gum with peanut butter, and also remove scratches on cds with peanut butter.... so who knows lol

It's probably more of a result of peanut butter oil than the peanut butter itself. Oil makes plastics shiny.

the oil is most likely what does the trick, but having it in a nice creamy form makes it easy to put on. ill do a round and put up pix once i get my car back from mazda.

p.s. chunky is killer on a pb&j but for the car stick to creamy, and dont bother trying to use it on the fender vents unless you can take them out to do it.

What would happen if you added jelly..OoO..

FYI, I used Dupli-Colour Bumper Black Vinyl Spray Paint (Satin Black) today and it looks ridiculously amazing.

"Dupli-Color Flexible Bumper Coating - Black, 311G" - Supercheap Auto New Zealand

I took the shrouds off, which gave me an opportunity to fix the broken and cracked 'tabs' that hold the shrouds in place.

I was all prepared to go out and buy two news ones, but these have come up so good, no need!

Heat gun, works wonders.

Can you post some pics? Just saw this stuff the other day and it looks like it might be descent.

Will post some pics soon.

One thing I will say, you must make sure the shrouds are clean as a whistle before using the dupli-colour, and be sure to shake the bejesus out of the can before spraying. It's a rubberised paint, so if it hasn't mixed properly, when it lands on the surface it can pull away from edges...
As I said, so happy with results, I am now going to do the lower rear bumper with the same stuff to match the newly painted shrouds...

Before & After...

Obviously the light conditions changed overnight so the pictures dont match, but you get the idea.

I'm very pleased with the result.

^^How was the ease of application?

It's a spray can, like spray paint, so application is just like paint. I took my shrouds off, to save masking, cleaned them thoroughly with Isopropyl Alcohol to remove all the road grime, wax etc, let them dry, then hung them and gave them 3 coats, about 20 minutes apart. I let them dry over night before reinstalling. Very straight forward.

Hmm, maybe someone can try just plasti-dip. You can apply it without removing the shroud, and just peel it off the over spray.

Best way to do it. https://www.rx8club.com/rx-8-show-sh...3/#post4249779

Mine are fading, which sucks </3

I plastidipped mine orange, and it works really well. Just gets dirty pretty quickly cause of the exhaust. Plus, it's had to spray the inside part, but it's possible and it helps protect it.

And why the hell would you do that?

:pat:
