Hi guys!

I am building spearguns for a 5-6 years. Most of them were wrapped with carbon cloth. Last two years I am using vacuum bagging for better results. I used to put one layer of epoxy resin and wait for 2-3  hours and then put carbon cloth. Recently I decide to use this spray adhesive for reducing waiting. Gun was prepared, sanded and coated with one layer of epoxy resin.  Sanded again with grit 100-10 and sprayed with adhesive. After 2-3 minutes I put on carbon cloth and proceed with resin, peel ply, breather cloth, vacuum bag and pump was turned on for several hours. I was satisfied how everything goes on.
Tommorom I remove speargun from bag. Looked great; but when cutting off exceed carbon cloth I noticed that it was not hard glued to guns body. On a first sight it was perfect but I was able to remove it like a socks.
Can anyone tell me what I was doing wrong?

Thx
