Jack, i use Aero Poxy Lite, it is very lite,strong and very easy to sand, but!!!!!!!!!!!!! you must use a gram scale and weigh it, to get the correct amts. Ron.  AP^

Sparky,

 So does this mean you're mixing micro balloons into your Epoxolite sometimes?
 I've always shyed away from Epoxolite because when I used it years ago, I remember it being hard as a rock after curing, and very difficult to sand. Maybe micro balloons is the secret?

Epoxolite does dry hard, but is easy to wet sand. I use 320 wet and it smoothes out just fine.

Maybe the trick is to get it smooth when you put it on. Some guys dip their fingers in alcohol, but I prefer water. Alcohol is a thinner for epoxy and I don't want to thin or slow down the set time. Keep dipping and smoothing and the Epoxolite fillets will be almost ready for finish when they dry.

I found Aeropoxy to be too finicky for my use. It must be weighed accurately with a gram scale and that's too much trouble. You can eyeball the portions for Epoxolite and it cures much faster.

I mix the Epoxolite 50-50 by weight. Then I add about 50% by volume of micro balloons. Be careful as the micro balloons will cause it to kick off FAST!! So only mix what you can work in 10 minutes.
