The one thing I don't like about WBP is having to seal the balsa with sanding sealer, which stinks and could make the glass not bond well.. I hate mixing different products like that.

What I do like is how easy WBP is to use and apply, less mess, and easier to get light in my book

So what if you bought WBP in the rattle can, and apply a very light coat, let it dry and apply a couple more very light.... just enough to seal the wood and not warp it... give a light sanding then put down your cloth and use WBP from the can like normal?

The next thing I glass I would like to try a test piece and see if it works...
