mixing it with fiberglass resin..mix them 50/50 or so. I probably mix closer to 60/40 bondo/resin...and then sometines even thicker on the bondo....go 50/50 at first and learn to adjust for your needs as you get more use to how it flows and hardens

I mix fiberglas resin.... get a blop of bondo mix your hardner in, , then 1/2 that amount of resin, mix with a couple drops of the resin hardner.. Works for me it is very runny

I usually mix a gallon size can of bondo & fiberglass resin (about60/40 ratio-more if needed during hot weather)at a time & add in tempra paint to give it a solid base color. When ready to use it, all I have to do is re-stir can ingredients & add my cure/hardner. This way I don't have to deal with all the mixing & measuring when I'm in a pinch for time, and also if I do a series of rocks the base color is consistent.
