Sounds like every Avalanche built before they took off the plastic cladding. I've seen a couple of Avalanche's redone with ArmorThane that looked perfect, and seemed to last.

i've had a number of vehicles where the plastic discolors. all i'm saying is blaming wiper fluid seems like a red herring.

Take it as you will, it's just my suggestion; don't have to listen to me :iono:

Ouch, that Project Farm video really pooped on 303. Been using it inside and out on every plastic part. Outside, it seems like it really is doing nothing on that video.
Bought a gallon of that and their fabric guard and have been using it for years now. Looks like it's Cerakote wipes from now on.

Good comparison. I have a bottle of Mother's Back to Black that isn't a spray - it's more of a lotion. I've had really good results with it, but it's a few years old. I'm wondering now if they still make it. I'll be checking out Cerakote when I run out.

I used AMMO Tire Mud with a foam applicator, its a dark cream/lotion that saturates the faded black plastic and provides a dull shine.

Worked great on my cowl, mirrors and rear valance.

they do still make/sell it. i use it on the truck fender flares about once a year when i get the overwhelming urge to repaint the plastic after looking at it faded for 8 months, but don't want to deal with pulling and resetting the trim clips. or discovering the lurking rust that's behind them.

Don’t remember where I saw it but there is a permanent fix that is like a paint for the plastic that restores it to back to new. But you need to tape off the the other parts, so it’s not as easy on just wiping it on.

Best way is to never let it fade to begin with. Almost impossible to restore back to factory look and have it stay that way. I have had some success with SONAX Plastic Restorer Gel.

Windshield wiper fluid with alcohol in it will discolor the plastics around your windshield for sure. Rain-x wiper fluid is also dynamite and will stain black plastics so I would avoid that. Overall though the most damaging thing is unprotected plastic in UV.

I use various 303 products on my interior stuff, but on any exterior plastic I have been using Wolfgang exterior trim sealant with a lot of success.

My dad just got a 2020 Chevy Blazer and it has a silly amount of black plastic on the body. Tried out Carpro Dlux ceramic coating for the plastic and wheels and eager to see how it holds up after a year.

Much has changed since this topic was posted. For those who want to bring back the blackness of the plastic trims, the best product as of todate is https://www.cerakote.com/shop/cerako...-trim-coat-kit. It is a ceramic coating for plastic trims. As soon as you apply it, it gives a rich black wet-look finish (for a more matte look, it needs to be wiped down). It is said to last more than 200 washes. It's been 3 months since I've applied it on the plastic trims like front bumper grill, fog light bezels, windshield cowls, mud guards, and even the rear bumper and have washed the car at least 4x. I'm happy to say that it does hold up very well unlike the "back to black" from Meguiar's & Mother's that only last for a few days. Another positive about CERAKOTE is it's quite inexpensive at $20 with 10 applicator wipes which is more than enough to be used on our cars for 2-3 times. You can check out the reviews of pro detailers on YouTube & skip the ones done by amateurs as they tend to mess up the application process that can cause streaking from uneven application.

There's two types of plastic trim - one is a dye which you will have to tape off the adjacent areas, and another is a typically clear/translucent lotion which the damaged plastic surface absorbs it.

I have not tried any dye solutions but for the latter you'll need to thoroughly clean the surface, apply and work the lotion into the surface multiple times. Depending how bad the initial conditions it'll look better and last about a few months after.

I tried their headlight coating kit and it worked pretty well. Sanding supplies could have been better but it worked. I missed a spot in the upper corners so of course i have some fading there but the parts i adequately covered are holding strong. Wouldn't hesitate to try their other stuff, but you do need to be very thorough in cleaning and degreasing if you're using ceramic coating.

As per instructions, it's recommended to wash the trim area with a dish soap in order to remove any oils & waxes for it to completely adhere on to.
