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

I sometimes get left with the same pattern, but it's normally when I've had a leaky bag

As above, i cure at 30 degrees and can safely de mould in 4 hours.

That's interesting, Im yet to have a fully airtight bag and had to leave pump running!!!. Do you know why it would cause this problem?. How do you clean your moulds when you've had this happen.

You can use mould cleaner from EC then re apply your release system, work on making air  tight bags and envelope bag if possible.
