Hi, all!
I have an opportunity to do a tri coat soon. Long Beach Blue Pearl in DuPont Chroma Base system. I did the big look through on this really impressive site last night for a relatable article and did find quite a few. I did develop a couple of other questions in so doing. It would seem that some notable contributors are 800 – 1000 grit “color” sanding their ground coats.
Someone else said they use scotchbrite pads, red and gray for solid colors and metalics respectively. Did I read this right?
I would have thought that such a practice would knock the metalics this way and that in a most undesireable way. Some other great things I gleaned was the practice of letting solvents really out gas and not to get too skippy about mid coating and top coating with one custom painter saying he perfers to wait overnight to proceed. BUT! Isn’t there and open time in which the manufacurer recommends you get after it? So….that’s it. #1 Do you lightly sand ground coats? AND #2 Can you wait up to overnight to top coat without having delamination problems down the line?? Going to pick up the paint and more importantly the data sheets later but anything you guys would care to add is MOST welcomed. THANKS!!Okay. Perhaps a shade less dynamic than I thought it to be………..
