2000 grit is enough to cut

[enkeivette]

So, I scratched the Vette really bad. Don't flip out, nearly all of it came out with wetsanding. But my point here, I started with 2000 grit to be conservative, and it really didn't take long at all to take the scratch out.

Maybe if you were doing an entire car I could see cutting with 1500 in one direction, then 2000 in the other to save time. But if you're working on a small area, 2000 is sufficient. Don't get carried away with a rougher grit and sand through your clear coat.

I used 2000 to get the hard water spots off my wifes Suburban and then had to polish the crap out of it to after to bring it back to a nice shine.

acid works best for water spots, but you have to know how to mix it right and get it on and off in a timely manner.

When I had the old K5, I took it wheeling through Manzanita brush out at Los Coyotes Indian Reservation. It scratched the hell out of the truck. I wet sanded the whole truck down with 1500 then 2000 and buffed it back. It takes forever and is a lot of work, but it worked great. I need to find some old pics of that truck.

That is very true. I didn't think anyone else actually had the balls to try that, really surprised you know.

Ya, use diluted wheel acid, spray it on and wash it off! Works miracles on water spots, glass too.

The detail guy Paul that use to work for Phil when he was at Crest use to do it.

tooth paste or metal polish also works well too

There are a few acids in the world, varying rather dramatically in strength. What acid are we talking about here? Muratic?

Fuck no. It's just wheel acid. It may actually be hydrochloric but if it is, I'm sure it's diluted.

[enkeivette]

And it's Muriatic, works great for cleaning melted aluminum off of iron cylinder walls. I would know.

Hydrofluoric acid is most commonly used in wheel acid. Hydrofluoric acid is what was in our wheel cleaner. Normally mixed at between 1 part acid to 3-4 parts water. If you mix it to strong or leave it on to long it will etch your glass and begin to strip the paint.

Ya, it's the kind of thing we did to customers cars but I would never do it to my own. Haha.
