Hi Folks,

I'm having my first attempt at making some simple wet lay CF shapes and using a glass sheet bonded to MDF backing as a mould base.

The part is flat 100mm x 50mm and has a 10mm radius on leading edge which has been formed using polyester body filler.

I'm following the how to guides & have coated the mould with 6 layers of Easy lease and brushed on the is EL2 (slow) resin.

Problem is that the resin seems to be repelled from some areas of the mould leaving areas where there is no resin at all!

I tried brushing it back over the uncovered areas but it just keeps opening up again a few minutes after its covered.

I used digital scales to accurately measure resin ratios and am working in clean area at 20 deg ambient temp. 

Any ideas?

Thanks,

David.

You want to remove it to a degree where you don't see it on the surface any more, it should look like it is gone. But you don't want to buff it so hard that you rub off the release agent.
