Just a note when using it as a sealer. I'm not sure what wood your using but on balsa the first dip is going to bubble pretty bad. I think as it soaks into the wood it pushes air out. Being patient here is the key. If you wait long enough the bubbles will stop coming to the surface, then you can cure it. If you cure the plug before the bubbles subside you'll have a ton of sanding to do. The second coat won't bubble near as bad, basically you can dip, hang, rotate and cure pretty quick.
