I have no vested interest in this product other than it performed
well beyond my expectations...
I recently was turned onto
Meguiar's "SCRATCH X 2.0" fine scratch and blemish remover. It's the best scratch and polishing compound I have ever used.
Last Monday I inadvertently scratched the driver's side of the Toaster with a tree branch... it's a long story that I'll spare you. Anyway, I initially used a standard white polishing compound and was able to get most of it out, but there were small sections that were still visible - especially on the front of the car, where the branch made initial contact.
On Labor Day I was showing my father-in-law the Toaster's new stripes and graphics - and the spot where it had gotten nailed. He's the one that put me onto the Meguiar's Scratch X 2.0 -- the Toaster is completely fixed, and the stuff worked quickly by hand on a dry terry cloth towel.
This morning, on a whim, I tried this stuff on the acid rain stains on the roof of my '80 Challenger. I have tried everything, (short of repainting), to get these damn stains off the roof and trunklid of the car - nothing has worked.
All I can say, (other than Oh my God!!! - several times), is that this stuff is truly amazing. I polished the roof by hand and the stains are nearly invisible.
The stains used to be clearly visible at certain angles and under certain light conditions. Now I have to get down almost level with the surfaces to even see the shadows of where they were. I'm tempted to try this stuff with a buffer - I think it might take the stains out completely.
Try this stuff, guys. It's really, really good stuff.
