Hi guys, I am looking for some advice regarding plug making for a cover I will do for my clutch casing. I have worked out/estimated that 3mm will be pretty darn strong, so have gone and purchased myself some 3mm sheet wax and some modelling clay. The item I want to make a cover for looks exactly like this, not my picture,but this is it:

Hey, thanks for the reply. I figured that would be the hassle. I was sorta hoping for a "zero to nil" answer as then it would point me in using cut sections immediately rather than have me faff around and then get to that answer having wasted time and sheet wax. Regarding filleting wax - I could mission and get some couriered here, maybe worth doing. How difficult is doing this with plasticine though? And would you say a flour based product would work (have tons at home), although I could just go and get some petroleum based stuff at a hobby store I suppose.
