Guys

I am after some advice please.

I've done a bit of wet layup and vacuum bag CF composite ( only simple stuff ! ) but am now looking to use infusion to create a flat panel ( approx 400mm x 900mm ) between two pieces of glass ( to be used as wing end plates on a hill climb car ). The construction would be :-

Gel coat-CF-Soric-CF-Gel coat

My question is, the two pieces of glass ( top and bottom mould ) will be larger than the composite stack so how do you stop the resin  taking the "easy route " around the composite stack and not wetting out the CF etc fully ? ( assuming the resin input is one end and the vacuum the other ).

Thanks in advance.

So I have another question / issue......I made some new flat panels. As expected using easylease the panels were no problem to peel the C/F off the glass. The new issue is the side that was against the glass has a steaky look to it.  I can't seem to get it off either. The pieces are real nice and useable but not perfect. any sugestions?

Thanks,  Dennis

Hi Dennis,

Yes, the trick to this is to 'buff' off the release agent after you apply it. Using a lint-free cloth (or microfibre) you can buff the release agent soon afetr applying it, especially if you've already built up a decent base-layer of release agent from a previous application. On glass particlarly you will find that once you've done this you can get lots of releases off the glass without re-applying the release agent.

It's got to be said that 'buffing off' release agent can and does remove some of it so this advice is only for those who are getting a good release and want to improve the (almost perfect) surface finish they're getting off glass.

You can buff this slight streakyness off the parts using something like Mirka Nanowax (wax/polish with a minute trace of ultrafine compound).
