DONT USE RESIN FROM YOUR LOCAL PARTS STORE. Its not the same as epoxy. That stuff is not water proof. There can be a nasty release of chemicals if it is not 100% cured. There was a thread on rc a while back a guy used that and lost his entire tank because it leached something into the tank. There is a place in centerville called woodcrafters ( I think) they have a 2 part epoxy that will work.
