Just getting started on a small pram project, got the wood and waiting on the box from raka to show up at the door to really get going. was thinking about doing the bed liner thing for the inside bottom (just the cheap stuff) searched the forum and saw a lot of talk and info about it, but no mention that I saw about applying it over epoxy, does it need a primer? or just a sanded surface to bite, any problem with curing over fresh epoxy even if blush has been washed off? Anyhow, got aways to go before doing any finishing just wandering how others apply it? primed or not.
Robert: Suggest you talk with Raka. It sounds like you are talking about the "brush on" type of liner. No experience on this. I used Rhino liner on the outside of our DB. It was applied over FG/Epoxy that had been "de-blushed" and well sanded with 80 grit to give the surface some "tooth" for bonding.
I applied Durabak to the interior bottom of my boat over oil-based paint that I had roughed up to provide tooth. lhedrick is right - the stuff is tough as nails, or tougher. Had I it to do over again, I might opt for the smooth product rather than the non-skid, as it would be easier to clean up.
