In a previous post about electrolysis some one mention parts cooking in the oven at 140 degree's fpr 20 mins after two coats of hammerite.

I like the idea of hardening the stuff but does it have to be wet or dry?

Cook it as the second coat is going off or wait until its dry?

Just dont want to stink the house out and upset the wife...

Yeah, that was me

I put it in as soon as the second coat was on. It seemed to do the trick. The coating was the best I've achieved with hammerite - almost powder-coat quality.

You will stunk the house out for a couple of days however, and this is sure to upset the wife. If I was doing this all the time, I would get a dedicated oven for it from the tidy tip.

Also, I found if you pre-heat the part for a short time before coating, the hammerite flows very well. It should also get some of the hydrogen out of the metal after electrolysis.


BTW, don't try it in a gas oven because VOCs are relased during the cure from the solvents in the paint.

i put mine in the oven and they came out a golden brown colour

I use a gas oven to cook hamerite. I use the lowest temperature and leave the door open a bit. If it gets too hot, the hamerite can blister or go brown

What were they, Yorkshire puddings?
