Thanks YS, i've been using the Bin also and really haven't had a problem with it but feel the marine primer might be a better way to go.
Iv'e used the marine oil primers from the can and they are great stuff , so if ya can spray it on it should make a good base for the createx.Only down side is, if it says "marine" on the can, they add another %100 to the price

Thanks,
Dave
