I did a third coat Glass Craft 3 on my first resin piece (800 x 400) last night and I checked it two hours later and was looking good - this morning it has several pits.

I did lots of preparation , I sanded it down to a flat smooth surface with a random orbital sander. I cleaned the surface many times , dried and blew it over with canned air. I washed it with acetone and made sure it was very dry. It was levelled out and pre heated before I did the pour. All the temps looked good and I made a cardboard box to cover it after the pour and I get this result. I am thinking that I have to change my brand of resin.

Simply can't carry on getting these results.

Is the resin thinner on the end with the dips?? 

Might be localised contamination or the resin has just cast a bit too thin in that area.  Some pictures would help here.


Here's a picture of the pits ......
