RE: Thinning epoxy with Acetone and adding filler?
Good thing about this discussion going on and on..............
It's been brought out that thinning epoxy that is used for structural is not recommended. But then, how many modelers thin epoxy when they're using it to glue stuff together.
Most thinning is done when fuelproofing a tank area or a firewall and are going to paint it on/in, and that's not really a structural job.
Seems like the discussion has been thorough and worthwhile.
