This product if they need to fill in gaps or connect to boards together this product works great you can form it to make curves so you don't have a 45° angle.

I have been using micro balloons in my hobby of building and flying RC model airplanes for over 50 years. Mix the resin and hardener together first and then add the micro balloons a little bit at a time until you get the desired consistency. Mixing them with epoxy will give a stronger bond but is nearly impossible to sand. Mixing them with finishing resin makes for lighter weight and easy sanding for filling in dings and hangar rash in foamies, fillets and damage repair.

I finally got a chance to use this. Mixed with the resin very well. Has a nice pink tint to it. And the price is right.

Have not yet had a chance to use the micro balloons. Will be using them as filler on some of my models, using superglue as a binder.

Be sure to wear a dust mask around using this stuff. It quickly aerosols when scooping it out, but not overly so, like a powder that seems to evaporate into the air vs staying on the spoon. One can scoop it out without issue.As to mixing it with resin I had varying results. The goal was to reduce how brittle epoxy resin is. I think it achieved this, with one or two plastic spoons worth in measure. This would also depend on how much resin its being put into. Stir until it has a kind of foamy creamy texturing, having premixed the resin beforehand.In cold casting into a silicon mold, I noticed that it tended to sink to the very bottom and create some small air pockets in the final casting. Using less of this powder reduced the issue but also left the resin more brittle. Using a lot of this powder may lead to a semi flexible casting. Elsewise I guess it works as intended. It also adds a white color to the mixture.I didn't experience a dust cloud when opening the initial foil seal, or afterwards. Just use care to open the lid slowly, and maybe wear some eye protection.
