RE: Mini seamaster
If you want to use epoxy on the fuselage, my practice is to use say 5 cc of each epoxy component and add 10 cc acetone and mix with an acid brush. I use the disposable 1 oz. mixing cups. Then I use the brush to apply the thinned epoxy. I did a set of HOB floats this afternoon and am waiting for the epox to finish curing. I find the acetone mixes better than alcohol, and evaporates better to allow the epoxy to cure, although curing does take longer than straight epoxy. I was using 6-minute epoxy today.
Once cured, I'll sand fairly smooth and put on a second coat of the same mixture. Finish sand and it's ready for paint. You can get a really smooth base for your paint this way.
