Thanks,

I think I've figured a better way to get those pesky gaps filled better, but I wanna run it past you guys first:
I'm using kwik seal fill in my gaps, as the mighty EVIL TED has directed, but some of my seams have *HORRENDOUSLY HUGE* gaps, like, fit a coin through them big. I've got like, 2 or 3 of them. My idea is this: can I take a card or something, lay it on the outside of the piece, fill the gap from the inside, and then remove the card and STILL have a smooth surface? Maybe let the kwik seal set for a few minutes before removing the card?
