Need information on durability, ease of application, etc. for clear resins. I'm making an outdoor sign for our church using wood letters glued to a board and painted, and intend to pour a clear liquid resin over the works, but have never used resin.
I've used it quite a bit to repair boats, but I also had an outdoor sign project I used it on. It can be rolled, brushed or poured on and levels out very nicely. Two coats of this stuff with a scuff sanding in between and your sign will be virtually bullet-proof.
Note: All the marine epoxy manufacturers recommend a high-quality marine spar varnish with UV inhibitors for a final finish! The epoxies do not hold up all that well outdoors with exposure to sunlight. Seems they haven't found a good way to add UV inhibitors to epoxy yet. I would therefore buy the compatible spar varnish from a marine supplier for sure. They are not inexpensive; starting from about $35, they range to over $80 (gallon) for the best UV protection.
