Yeah they are bad on the bottom. After messing with some others that I made I'm realizing that it is mostly because of me sanding them...must be opening up voids in the microballoons like said earlier. I've resorted to VERY HEAVILY coating them in high solids filling primer with multiple coats, some times having to puddle the primer and rub it into the pin hole to release the air. It has been working but takes for ever and I cant seem to find any of this thin two part glazing putty Ive read about, I can only find the stuff in the tube that has not been recomended here...any advise where to get it or can some one attach a pict or link Chris

Great advise. Kind of odd tho... I'm using silicone molds that are perfectly smooth and the voids are on the bottom, so maybe the balloons as settling. With the small size of the balloons it seems like you wouldn't even notice rupturing a few while sanding. Good to know I can use bondo but would rather get the casts smooth on their own

Sry about the pict link. Theses are the voids I was talking about

I've reciently started resin casting some lures with micro balloons and have a problem with a "texture" for lack of a better term in the bottoms. The small voids won't sand out without found WAY into the cast. Any inputs on the reason these exist or any good fillers to smooth them out is greatly appreciated. BTW these are still test ones to learn with... Please be gentle.
