poly/epoxy adhesion for glass-ons

Just got a great set of Hobie glass-ons from True Ames for the fish (yeah…isn’t everyone making one?). Only concern; fish is gonna be epoxy over 2#eps; fins are probably poly over hexcell. Wondering if there are any precautions I should take when glassing them on/glossing afterwards to insure that I have good adhesion between the supporting structure in epoxy and the fin (in poly). Also wondering about the gloss coat…am I going to have tons of chipping? Ideas? Suggestions? Experiences?


No problem,no chipping as long as the areas are prepped with proper sanding

.Have fun…

And 50 grit is proper sanding.

Thanks gents. Outta town in for a couple of weeks; will post photos once I’m through!
