Mould condition after releasing part.

Hi all,

Still playing around trying to make my wheel spats. My moulds are made from ec epoxy  tooling gel coat and I've been using easylease release agent. One of my moulds has had 3 parts out of it now but what im noticing each time I de mould is that the glossy surface of the mould is left with a pattern of the cloth which I assume is traces of cured resin. Each time I've washed the moulds in soap and water and also used mould cleaner  try and remove it and then re applied the easylease as from scratch. Is this normal with wet lay up/vacuum bagging or am I going wrong??

How critical is the shelf life of easylease?, Mine (foolishly) came of ebay, the tin hadn't been opened but its age is anyones guess!!.  

Cheers

Craig

Great, thanks for all the help everyone, the bits left behind in mine do feel more than just a film, the tiny bits pick off with your nail. I'll have another go, concentrating on by bag seal and perhaps leave it longer before de moulding.

Cheers
