As nick says epoxy is good but I will add that epoxy doesn't contain the nasty isocyanate but still best to wear a carbon filter mask as a minimumI would take the advice from the guy who is painting it but by far the best bet may be to give it a coat of epoxy primer. Im old skool and have recently got into epoxy but its good stuff and unless you have full air fed facilities the only option is a cellulose primer which is too unstable. Just my opinion and am happy to be shot down.

Cheers for your help again.
I'll grab another tin of the epoxy I've got the hardener for.
I'll grab a filler primer too at the same time to go over the top. What do you guys recommend? My painter will be using 2k base and lacquer, but he said any old filler primer will do.
Edited to add, do I need filler primer or high build primer? And everything seems to be 1k/2k. Do I need to use 2k for every stage. Does a filler/high build primer need to be 2k if it's between epoxy and 2k base?
Cheers for the replies.
I'll stick with a couple of coats of epoxy rather than a high build.
And to confirm, if my prep wasn't the best first time round and the epoxy highlights it, can I key and fill over the epoxy?
If your thinking of leaving it in primer for any time I would seal it with a coat of epoxy otherwise it will take in moisture.
Does that apply for 2K primers too? I thought that being activated might have made it waterproof like epoxy.
My project will be living outside, and won't be completed in a hurry. I'm planning Lechlar epoxy as a base coat, then a yet to be determined filler/primer, and need to know if I should plan to apply another quick epoxy coat over the top of the filler or not.
