I just finished spaying the flaps and elevators on my SCARF Stang, and the base color is Silver. I did an absolute terrible sanding job on them and they look like H%&&. As soon as they dry a day or two I'll wet sand them and try again. On Windy's videos he uses M600 and 600 grit when sanding silver, well I haven't priced it but I hear the M600 is really $$$$$. What do you guys use in your wet sanding ? and is 600 paper the grit to use ? I just want them to look decent and not like H%&&. Thanks

Suggest you get a nod from someone in the automotive painting area. I did that and am
pleased to find out that the info I was given seems to be legit. Purchase some "Dawn" liquid
soap, the original (blue colored stuff) and add to the sanding water, caution, use just a drop or
three at most and gently mix then use one of the following automotive wet sand grits unless you
are really needing some serious sanding; 1000, 1500 or 2500. As with all wet sanding paper/cloth
cut to size needed and then drop them into the sanding solution for a few minutes then sand away
but remember to keep the paper wet and clean by dipping in sanding solution.
Hope this helps. Oh yes don't forget the Meguiar's when done. Check with Robert or others
to get some tips on the wax.

Hi Lee,
Marv gave a pretty good run down. Water with a tiny bit of Dawn is a good wetting agent and keeps the paper from clogging.
I *think* the 600 Windy uses to sand silver is correct, BUT, I *think* he then sprays a final coat of silver before his colors. I know that forever (does he still??) Windy used Sig silver for his substrate and blocking coat. Silver shows every tiny flaw that is in the raw finish. That was why he was using it! When the silver is perfect, there are no flaws in the color finish. The 600 was for rapid removal of material while safeguarding a little bit from sanding through to the base. If you are going to use silver for the color (which is what I gather) then sand that coat down and spray a light coat followed by a fiarly wet one. Apply clear before sanding again. Any time you sand raw silver, it will not look good at all. You will have to rub out clear coats.
