Lightweight alternative to Bondo.

[DNT 2.5]

For years i have been using a product called Microballoons for my model airplane body filling needs. They are basically a little glass bubble that you mix with epoxy. It makes a VERY strong lightweight body filler. A link to a website is http://www.conservationresources.com/Ma ... n36_03.htm. It may seem like alot of money, but it is really really light. $17 is literally a TUB full of it. Just to let you guys know.

Like Floam made of glass, but it hardens like a rock

Is it impact resistant? Does it sand well?

ITs sands very well, and it is pretty impact resistant. its not quite as strong as bondo, but its ALOT lighter.
