ok well 1st off smart ass you didn't state one word about the underside of the hood rockers or valance panel .
instead of getting your back up and trying your best to be a total ass you may want to think about taking some advice from some one that has restored countless porsches of the last 40 years and that worked for porsches coatings dept.
1st you picked the wrong chip guard you should have gone with u-pols chip guard and bought the white color then tinted it to match the underside of the chassis .
you also do this if your restoring your fuel tank .
as for painting over SKS as SKS is made by U-pol again you picked the wrong crap .
you as i stated if you have a primer you can mix as a sealer ( you said primer and not a dam thing about sealer or if you can mix the primer you have as a sealer ) then you would mix it as a sealer and spray one but no more then two coats of its going wet on wet after it flashes off you then would go to top coat .
as you repeat it ! the answer is NO it's not the best but it will work .
try reading your TDS they tell you every thing you need to know .
fyi wurth doesn't make products they take other peoples products and put there own name on them .
