Hi, I have used you GC50 clear gel coat on a couple of different projects

1. to make a flat carbon fibre panel, using a glass sheet
2. carbon fibre dash board, using a contiboard and plastic home made mould

for both I used Easy-lease release agent. 

My problem is when I brush out the gelcoat I seem to get thin streaks in the gelcoat where the gel doesn't want to flow?

Any idea what I'm doing wrong please.

thanks

Easylease is a very slippery release agent which is what makes it so good for releases. However it does mean it can be a nightmare to paint resin on without it fisheyeing.

Some people have success by using a layer of no 8 mould release wax to help stop the fisheyeing.

Spraying is the best way by far of applying the gelcoat though.

Well,
I have given up on the GC50!
Just not worth the hassle in brush application.
Sorry,
but it's not reliable enough to risk expensive cf/epoxy! 

I've been looking for alternatives and found a product from a different supplier.

I had similar problems with a brush, and found that the small sponge that you do your washing up with worked really well!! But don't hold me to that! That's for small moulds, I now spray the bigger ones.

I'm sorry you find it too difficult for brush application.  As said before, brush application isnt easy and GC50 by far suits spray application.

You can talk about other suppliers products anywhere in the forum except the Easy Composites Technical Support area as we aim to focus this area on problems and support related to our own products. We don't want to cause confusion for new customers looking for specific product advise.

Of course asking if we supply X, Y and Z or do an alternative etc is fine.

If you want to discuss the alternative product in this thread, please go ahead and let me know and i can move the thread into the main part of the forum to get a wider exposure and broader discussion.
