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?

Details:

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?

Thanks all!

A good primer is a must on the barrier coat to get the bottom paint to properly adhere. A good scuff with 80 grit on the barrier coat then a primer should do the trick.

rubbing alcohol isopropal contains a very small amount of oil bittering agent, not a good thing. "IF" you can obtain pure alcohol it is much better.

Do you know of a good type/brand of primer appropriate for this?

FstBttms, Thank you - I'll ask this question there too.

desert rat, sorry I said rubbing alcohol but in fact I use denatured alcohol bought from the solvent section at Lowe's/Homedepot. Is denatured alc any better or worse than acetone? Acetone dries so fast the rag is often dry before I'm done wiping down the surface..

Ask the paint manufacturer. Nobody knows paint better than the company that makes it.

Ditto that! As I recall, there's a customer service number on the can's label. I have called them and talked directly with a technician who really knew the products.

It is in their best interest that you get good long term results.

Then it won't let me post a new thread until an administrator activates my account. Sheesh - all for a paint forum!
