Ablative paint to cured barrier coat?
When I was applying barrier coat to my rudder this past weekend (after many repairs), it never occurred to me that I would want to apply the bottom paint (Micron extra) in the "hot" fashion before full cure.
Well, now I realize that was a mistake. Given that, what is the best method to apply the ablative over the barrier coat?
Barrier coat: 5 coats of epoxy, the last 3 of which were mixed with West 422 barrier coat additive.
Paint: Micron extra
My best guess of what to do:
1)Clean off amine blush by washing entire surface with warm water and a blue scrubby.
2) Lightly scuff surface with 220 grit sandpaper
3) Wipe down with rubbing alcohol for final dust/grease removal
4) Paint with bottom paint.
How long between coats of bottom paint?
Any tips/tricks/advice to improve my plan?
