Gavin I have been using clear finger nail polish to fill dents on pf wood grain where this is no detail eg. near the flippers. I was thinking of using it on dished pf round plastic's. I remember you were trying a two pack self leveling product (what the spiders was preserved in ) Did you ever find out?

have a problem here... i dont have any sunken inserts to experiment with. Only ones i have are on other peoples PF's and i cant experiment with these. Anyone has a sunken insert lying around...send it to me and ill give it a go
