Someone suggested awhile back that it might be possible to coat a blade with hi temp engine paint prior to heat treating as a way of reducing scale instead of wrapping with stainless foil. Has anyone ever heard of this, tried it or have any opinion whether this would be a worthwhile idea?
 
It will most likely burn off in the high heat and flames...A forge is hotter than a header...And then you will still have to clean off the residue...:eek:

A better idea might be to try Turco, a high temp coating designed for heat treating...

I've used it a few times and it leaves your steel clean and ready to finish...

Not sure where to buy it...Any help?

I beleive Brownells carries a product called PBC, to stop the carburization during HT. There is a good thread, over on the CKD, about the usage of PBC, by Terry Primos. You might also want to try dipping a warm blade in borax and water, before HT.

Thanks for the tips guys. I will check out my Brownells catalog, CKD and also give the borax some consideration. Cleaning off the scale after heat treat sure is a pain in the butt, yet it seems like the foil is awfully expensive.
 
Turco worked well for me on oil quench steels, but didnt work on air hardening steels due to the higher temps involved. Foil is cheap compared to grinding belts and labor.
