I picked up a couple of Stanley short bevel chisel's.... not sure how new or old they are but they are heavy..... lot of metal in them. One has been used for something but the others are new. All of them are coated with a thick clear finish that is really stuck on. The one that was used did not even have the coating taken off nor did it come off in use. I started scraping it off on one of them and it does not want to come off!

The picture is not too clear but maybe that will help someone to see what I'm talking about. My guess is the former user found they did not work well and did not know about the coating or found out how hard it was to get off and said to heck with them......

I'm thinking of a power wire brush unless someone else has an idea????????

You were right - the photo didn't show much, but before I'd use a wire brush, I'd try some sort of solvent.

Up to the minute scores:
Acetone 0 Coating 1
Min. Spirits 0 Coating 1
Paint Thinner 0 Coating 1

So far the coating is winning all the games............

Try the scarey sharp method starting with a 400 grit and move upward from there.

Be sure to post the new score :~)

Try lacquer thinner, it works for me.

I did not try the sand paper yet..... that might be next.
I checked and I have no lacquer thinner so that is on hold until I go to the hardware store.

6" wire brush mounted on a grinder 0 Coating 1

I worked for about a minute and barely touch the coating! At that rate I will be about an hour a chisel...... I'm going to invest more it supplies getting the coating off then I spent on the chisel's.

Is this coating common now? I have never had this on any of the other tools I've purchased and will avoid tools with this on in the future......

You may have hardened it further with some of those chemicals

If acetone wont take it off, no solvent will. Acetone is the strongest solvent you can get.

Sounds like the surface has taken on a finish of its own. Not uncommon with heat treated metals. If it is nothing will remove it....even sandpaper..maybe shine it a little.

I did a bit of surfing and found this reference: "Blades electrophoretic lacquered for protection against corrosion"....... I guess that is what that stuff is but the metal finish is very poor so I was planning on getting the grooves out of the back and polishing that surface then work the bevel....... etc. Now I'm thinking I'll try them as they are and see how the coating effects them, they will of course need to be sharpened on a grinder which will remove the coating on that section....... I wonder what the package/box/plastic box said about this finish?????
