Good day
I'll be as brief and to the point as possible.
After many, many hours of preparation, I am ready to begin the painting process of my topside.
Products being used are International's Pre-Kote as my undercoats (no primer needed) and Toplac as my finishing coats.
2.5 coats of undercoat and 2.5 coats of finish. The 1/2 coats are a blend of the two products 50/50.
Ok. The questions are coming soon.
International recommend that the undercoat is applied to a surface abraded to 180-230 grit.
As I have had to use 80 grit to remove the old paint completely, my first question is can I apply the first coat of undercoat to the 80 grit surface?
To my thinking, 80 will give me a better key thus better adhesion.
or should I sand up to 180 before applying first coat?
Following on, if I do apply to the 80 grit surface, will I need to sand up to 180 for the next coat? or ever?
Which leads to my last question, should I be sanding between each coat? or between undercoat and finish coats?
I hope someone with some experience in boat painting can offer some advice.
Thanks for your time.
