I am using a MDF mould buck which I need to 'smooth' with primer and top coat of paint - I propose to use a nitro-acrylic paint - will that work with a gel coat and polyester resin which will be used to make the mould?

Thanks

Thanks for all the useful advice!

I have a problem now because the buck is now painted with acrylic-nitro - I had read that Polyester on acrylic was ok but not the other way around. Can I use an epoxy on the acrylic paint? Hopefully I don’t need to strip all the paint off - that would be a job...

I will cover the steel with a pure epoxy coat before bonding it into the piece in a second epoxy carbon fibre hand lay operation.

Then I will join the front and back with epoxy adhesive.

Then I will make some holes and inject some 4 pound resin.

Thanks
