I picked up used set of High-Top Fender flares and they are all blotchy. Car Guys Plastic Restorer had been used on them previously and from I have read on reviews I think this product may have contributed to the blotchiness. Any ideas on cleaning this up?

Back when I had my TJ I used a product called Forever Black, it is essentially a dye. Worked very well to recondition faded plastic fenders.

The thing is these aren’t faded. The PO used the product to clean them up, I think, and when they arrived to me they’re blotchy. I need to even put the color.

That product is not a dye and can be washed off. Try a solution of dawn dishwashing detergent to wash them clean. Don’t you just hate POs?! :tomatoes:

I’ve never used it, but I looked it up at their website. This “This is a newly developed, water-based polymer formula that contains a very special and newly PATENTED polymer additive.” may be the problem. Seems to me to be the same as adding floor wax such as mop & glo, or Zep. I have used M&G on an old RV to rejuvenate the dull faded fiberglass (took several applications, plus hours of prep to get it really clean first), and also put a nice shine on the metal frames and rubber seals around the windows. Looked great, but it needed to be reapplied just like car wax or floor wax from time to time. Try using some ammonia, or floor stripper to remove the stuff.

i would not use ammonia or any floor stripper in those flares.

I only suggested it if the blotches verse caused by the polymers then perhaps Ammonia will remove it. I don’t imagine it would make it worse...

Rubbing Alcohol and then Aerospace 303 seems to have done the trick. We will see how it does long term.

Try to stay away from anything with petroleum base if ya can. 303 is good.

Sorry to say the rubbing alcohol and 303 did not fix the fronts. They are clean not but look grey. I wonder if it's from sitting in a box for 4 years since they were NOS when purchased by PO.

post a photo of the blotchiness. Most stock fenders look terrible pretty fast. I think they maybe made of recycled water bottles.

Don't laugh, but I used some black paste wax shoe polish on some plastic once and it wasn't too bad.

I just tried Mother’s Back to Black. It made zero difference. :(

It's like there is a haze over the plastic. Like a pain job that needs buffying out.

I had a similar issue when I first got my jeep. When I was ready to just rip them off I tried some Hot Shot wheel and tire cleaner, then back to black and it seemed to work. It probably wasn't the best idea, but the results were pretty good. If you try it, do your best not to get the cleaner on the painted surfaces.

I am going to try Mother's Back to Black Heavy Duty Trim Cleaner next. I also called my paint and body guy to get his opinion. we will see what he says.

Paint guy said in his opinion it’s the plastic. He suggested heat gun/ hair drier “trick.” I have read this is a bad idea though.
Still looking for solution.
BTW he said he would not paint them as they are textured and if they chip they cannot be spot painted due to the texture. I agree. I had a similar issue with a textured bumper on my previous truck.
