Footstrap plug stripped on 07 Carve

[Clewless]

Hi, Don't know if anyone can help me, but one of my footstraps pulled out of the deck the other day, first time out after I had repositioned them. The plasticky - rubbery lining into which the self tappers go had failed, and some of it was stuck on the screw. I got hold of a thicker screw, but there was nothing for that to grip onto.

The question is, is there anything available to renew this lining... Ola over on the Boards forum suggested a possible liquid fix...?


Thanks in advance.
