I have been using it for years on my show trucks and daily drivers and I started using it on my denim pewter sg. It works great! I was worried about what I would use on this color but this stuff is the best! I will take some pictures tomorrow, I only did half the bike because its like 27 degrees. I typically like to rinse off the dirt and grime first but this waterless wash is really great.
I agree Mike and after I use the Spray and Wipe I go over it with Spray and Gloss for the POP. Poorboy's products are the easiest to apply and last longer than any I've ever used.
