I had issues with maple, cpes has solved most of the splitting, but you need a few coats. My first few batches didn't get sealed well enough with one application, and to my great embarassment, split.
I have about a gallon and then some of watery thin(as compared to e-tex or devcon) boat building epoxy and an oven to heat the blanks. Would that work?
I have a few questions for you guys that do the epoxy thing. The big one is how do you coat the outside AND the throughhole and still have a way to hang it to cure? The other question is do you just use a bunch of epoxy and spin it like you would for a finish coat or do you try and get as thin a coat as possible? Also, could I use the boat building epoxy for a finish coat too, or am I better off sticking to e-tex and devcon?
I know I'm asking a lot of questions and I should just experiment but it can't hurt to get some advice from folks that have done it before.
The cpes is the thinnest of the epoxies i know of, the boat epoxies are a little heavier but heating before mixing may help.
The inside coating is the reason for using thin as it works itself down the thru hole and belly holes. you can use a foam brush to take off the excess dripping and coat the outside. Use a pipe cleaner soaked in epoxy to run thru the holes to be sure the inside is covered.
You can put stainless steel screws on an angle over your bench and hang the belly holes of the plug on them to dry.
If you have a gallon of the boat epoxy it would sure be worth a try as a clear coat.
