Thank you all for your help and advices... I am producing a male plug to create female moulds to pull off castings...

I had moved on to glass the plug with finishing resin. I forgot the weight of the cloth but it has the same thickness as t-shirt material... I applied a second coat of resin to fill the gaps in the weave and when it had dried, I wet sanded the entire plug with 400 grit sand paper.

I located some low spots in the sanded plug. I will follow Bill's method of coating the entire plug with a thick layer of putty... I have no success locating bondo putty in Singapore.. so I am testing various brands of putty to find one which is easy to spread and will sand well... the pics show the plug after sanding down with 400 grit sandpaper and the various putties I am testing.

By the way, is there a trick on how to lay an even coat of putty into the plug?
