Reading some of the more recent posts, I'm getting worried that when I get the last coat on (my '76 VW bus)and I'm ready to finish, I'm going to wetsand, and then the cheap buffer I have will not bring the shine back to even what I have from the final coat. What happens if I skip the last wetsand at 1500 or 2000 grit, and just use the polishing compound and the wax? Thanks
