The major issues I have is the finish is rubbish. I didn't go up the grades of sandpaper long enough and you can see fine lines. There's little white dots in the resin which I believe are air bubbles. Hammering it with a low-temp heat gun didn't get rid of all the air, so it appears. Also the resin became contaminated as I re-used a brush (washed and soaked in acetone) with fresh resin for the final layer, but the resin dried as a complete fog instead of nice and clear. So about 8 hours of sanding pursued to get it to a semi-finished state, as above. You can kind of see the fogged resin along the bottom of the part. I've learnt from that to use a new brush for each layer.
