Hi John,

Did you paint the deck and the hull?

What was original color of the deck and the hull before you started.

Was the Interlux TopLac easy to use?

What were the conditions like when you applied the Toplac?

Did you apply primer and then finish coats?
 
Thanks,

Bob

I just repainted my alberg 30, white she was black. I used  Interlux TopLac
It's a silacone polymer 1 part paint. It went on great and looks like  I
sprayed it!
