Group: Forum Members Posts: 59, Visits: 373	Prior to applying a finishing layer of coating resin i thought it would be a good idea to degass it as ive been getting micro bubbles that collect polish. However for me the degassing process seems to add more bubbles than it get rid of. Curently Im poring this resin by hand, "tipping out" with a brush and then using a heat gun to pop bubbles. which is OK but id like to degass first. here are some pics. Mixed Coating Resin prior to de-gassing Resin during degassing - i left it like this for 2 or 3 minutes until the bubbles collapsed - then locked off the pump and vented the chamber vacum reading resin after venting .... after waiting 5 mins to see if the bubbles float out.... i tried degassing it again and again but it didnt improve, so after an hour, by which time it had started to warm warm up. i binned it and used the old method. What is going wrong ? Thanks Ben

Is it possible that this is not enough vacuum ? Ben
