I've got some black plastic fender wells in good physical condition except for a dried white film in varying "shades".

I've tried engine degreaser at the quarter car wash, Easy-Off oven cleaner, and Simple Green with poor results.

As a last resort, I have taken MEK (Methyl Ethyl Keytone) with 00 steel wool followed by Mineral Spirits. It looks better, but it's not an even cleaning.

I've seen where some of you guys have used spray paint (SEM, Bumper Black, Krylon, etc) but no reports on long tern success with the engine bay heat and wire bundles and hoses rubbing against it.

Any good or bad reports out there on painting or a better way to clean than MEK?

I have a crappy set that I'm using as a test bed.

TIA.

how much time do you have? you can wet sand them starting with 400 in the real bad areas and then 800 then 1000..... after sanding there is a plastic polish you can use that works great but i can't think of the name right now. you would likely have 40 hours or more in them but it works. i have no idea on painting them.

plexus maybe ? its a popular plastic polish

Im watching this thread as my fender wells sound like yours good condition but faded like areas (whitish greyish) cleaning didnt seem to do anything

a guy at the local carquest said the SEM bumper dye worked really well on his jeep fender flares that had faded....after a couple OR outings no scratches showed at all

The SEM bumper dye is different (or at least marketed different) than their interior vinyl dye (which Im very happy with BTW)

I've used black shoe polish after I had cleaned the plastic w/ Easy Off and it turned out pretty good...

I washed them down, hit them with a red scuffing pad, wiped them down with amonia, sprayed them with plastic primer & them painted with a plastic semi gloss paint. Rattle can paint and they always come out good, i'm doing my 3rd set right now. Looking at about $25 - 30 in materials & a couple of hours of work. FYI I remove them for this process

Im glad this thread came back up.

I scrubbed mine with dawn and a stiff bristle brush, they were clean but discolored as described above.

I scrubbed them w fine steel wool, again better but still not great.

I then used 3m restore black which is suspect is similar to back to black as promoted above by pilot and paratrooper

after the restore black they looked so good my friend who had seen them before thought i bought new ones...theyre not perfect but they went from terrible to very good.

I know this is an old thread, but does anybody know what kind of plastic was used for the front fender liners? Thanks!
