Part 1
Geezzzz where to start lol. All this talk about,high end paints , special windows , training , delamination , paint falling off , windows , crap , where did all this come from . Oh by the way , I am an award winning airbrush artist, and not just vans. I have worked on as small as miniature Harleys to 53 foot trailers , even restored 100 year old painting.So credentials? Do not take me there.
All the art i do is over a layer of clear sanded with 800 wet, and never have i had to worry about scratches so this is a myth.
As for top clearing. Once a surfaced is cleared and wet sanded , according to the Dupont rep i deal with and the shop that does my clear there is no window to re -clear. The only window for Dupont is when you are basing, once base is applied you have 16 hours max to lay the clear on it . This only applies to the base not re-clearing.
