I'm pretty sure this product is not recommended by any car company or paint mfg. I'm certainly NOT recommending it either.
However, it is about the only product that I've used that will cut heavy oxidation and kill off the mold and moss on a car that has sat for years. I use soft scrub with bleach with a terry towel and lots of water.
It actually stopped raining long enough this morning that I was able to go out and start on the paint on my project car.
It should be pretty obvious in the photo that the front door was done and the back door is untouched.
