I have just had a phone call from a customer we did a repair for 3 days ago. it was a standard bullseye repair and all but the pit was invisible when finished. He reckons a line has apppeared around the outer circumference of the bullseye. My thinking is that i didn't cure it enough, and as it cured fully the resin contracted slightly. 2 questions: Is this the cause and is there anything i can do to rectify it?
Cheers (I'll get there eventually!!!)
