Yes, I understand there are most likely easier ways. I don't recall anyone posting that Humbrol paints were fuel proof though. I remember them in one hobby shop from 20 years back..sold in little metal cans. If anyone has more info on Humbrol please chime in.

As far as the epoxy mix goes, I completely emptied each tube as much as it would allow. But it is hard to tell since there were some air pockets on the resin side.

After the oven heating, it's useable now, so that's the main thing. It wasn't any major project. And it was a good way to test the method. It's just an engine test stand, so it was no big deal if it didn't work out.

I know there are other simpler ways to go about it. Next time I will give the clear automotive spray a try.
