This probably belongs in another forum, but I need maximum exposure and some quick replies.

I am assemblying a PacAero GeeBeeY and have hit a major snag. What I consider huge gaps in two places on the vertical stabilizer. Gaps that are tapered and up to an 1/8" of an inch in some places. Sanding will fix part of the problem. But...

I need some suggestions for filling the gaps that will complement Vert Stab strength, not just fill the gap. Help!

the easiest way is probably with micro balloons and epoxy

Baking soda smoothed into the gap, and CyA. Makes a very strong joint. Just make it smooth from the start so you don't have to sand it.

Darn, I had forgot about the baking soda thing. thanks, and it is the white color I need.

Cool.
