anti foul and primer coat for steel hull

[charlieatsea]

I spent a fortune on Awl grip anti foul last year with an epoxy primer and now the under side looks like it is suffering from teenage ACNE. There are small bubbles everywhere just the anti foul. i presume i must have put the last of two anti foul coats when it was damp etc. ? It has nothing to do with electolysis ? Is there another product on the european market that works well for steel and will not break too much my wallet ? The yacht in question is a Wibo 9.30 sail boat
many thanks

What was under the epoxy primer?

[charlieatsea]

hello,
what was under was an old thin coat of an epoxy primer i must have put on 3 yrs ago. The yard painters said it would be ok as long as it was sanded and cleaned back then you could build other coats of primer on top. The primer was definatly compatible with the anti foul..

And the name of the epoxy primer was?

It could've been the application and prep, not the Awlgrip (I didn't know they made an anti-foul, actually).

For the record, I do not shop for steel boat paints at the marine store. I shop at the oil rig platform/ocean buoy store (Ameron, Endura, etc.). Industrial-grade mindsets work well when you own steel.
