Sealing the mugs to make it leak proof

[sailer5373]

Wondering what I can use to make my wooden mug leak proof?  I have a two part resin that I use on horizontal surfaces but if I put it on the mug sides it just sags down to the bottom.  It will seal it beautifully.  Is there a product out there I can use to brush on and beer liquid proof it?

When I made mine, (out of plywood yet) it had alot of voids and did leak at first. I just kept coating it with polyurethane and letting it dry for several hours before testing it again. I just used water (saved the beer for last )
I am one of those that believe that most if not all modern finishes are food safe once they are fully cured.
I guess you could use shellac the same way but, it might take more coats. Shellac is used on medcine pills and candy (think M&Ms) so we know that it is food safe.

Thanks Roger for your speedy reply,...............I guess that's why your called rapid. lol  I think shellac is dissolved by alcohol though.  Wouldn't want to waste it.  I think I'll do like you,  save it to the final test.   Thanks again.
