I know right? You metal 'prepped' it when you sandblasted it. Its down to bare metal, all you have to do now is clean the dust and possible oil contamination from touching or the oils in the compressed air used for blasting. DX330.
I had a friend that insisted the proper finish sanding before base/clear was 600 grit WET. I actually had to replace some of the areas he did with that IDEA with new metal! Come to find out some automotive restoration programs are actually teaching 600 wet before base/clear. Wow! The graduate who told me that and now owns his own restoration business agrees that was the worst instruction he ever got. 400 grit dry, sealer and done!
Whats sad to me is that experts from all over the world in this profession do not get together and post actual working instruction for everyone to follow. Maybe in 30 years or so. This would eliminate all of this conjecture. With nobody on the same page, we just do what works for us. Its just a truck right?
