One thing I have learned with Dupont is,
You USE what THEY recommend NOT what "you think" is best.
Dupont knows what THEIR paint will cover over and deviating from THEIR requirement no matter how rational it "might" be could be a BIG mistake.
I've learned from MY mistakes,as well as others using Dupont and "if" they say "Use a Orange shade primer under Our White base" THAT is what I WILL use.
This is an exaggerated example but with Dupont base's,Unless you want to spend a bunch more $$$ for more base to cover and possibly end up with a different shade top coat,You "best" use what they recommend.
Hot Hues is a good custom paint line BUT, It's STILL Dupont.......
