simple Hi-Tek coating

[Scorpius]

I have them in convection oven with fan to move air at lowest setting being 100 degrees to ensure they dry. Mixing up my gun metal rifle batch now.

Funny...gun metal at least starts out looking blue for some reason.




Out and cooling before all testing



And the gunmetal now out of oven


On to second coat.... rub, fingernail and hammer test passed!

Hi-tek I was wondering how hard should I press down when I'm doing the wipe test?

I went back and read my post and it wasn't clear so I'll try again. All of the coatings have been mixed and yes the liquid is catalyzed. They have been sitting around
in different containers. Some are too small of an amount to start using for a batch of bullets. So I'm going to throw them all into one container and use it. I'm not concerned about the color as much as the performance which, up to this point, has not disappointed me.

Thanks for the reply.

The wipe test is simply to see if you had set the coating with baking.
If it comes off with solvent, after baking, then the next coating mixture will strip off previous coating and will make a mess..
Once a coating has set, correctly, you can rub as much as you like, and coating should not come off as it is no longer soluble in solvent.

That information is included on coating instructions already.

All done. Settled on a third coat. Love the color

If you rub too hard the coating will come off by mechanical action rather than chemical.

Marky, that looks very Heath Robinson-ish sitting on your bench.

Scorpius, yep, Gunmetal comes out a gorgeous blue when mixed, it's rather a shame it changes colour when baking.

BULLSCHITE!!!!!!!!!!!
If the coating is applied and baked correctly, the ONLY way to get it off is by bloody removing alloy and coating together.
Jesus!!!!!!
Stop spreading BULLSCHITE info....

It's not finished.

This is the 45-70 first coat, of the mixed together colors, wipe and smash test. It looks like the color I will not be able to duplicate is going to be kinda like Army green. Just a tad of color on wipe, it looks like the dark blue, after 390-400 F for 12 minutes. Two more coats and loadem up to go to the range.

Is this the liquid coating or the powdered stuff. or both??

Ad a bit more catalyst to the mix if you have some.
I mix a heap of different colour leftovers together all the time. saves tipping it out.

It's a little bit of the liquid Gold 1035, some powder Bronze 500, a little powder Gun Metal, and powder Dark Blue. There wasn't enough of the 1035, 500 and Gun Metal to coat another batch with three coats so those are small amounts. After throwing it all in one container I should have enough for another 20 or 30 lbs of bullets.

Will give you a photo of the finished bullet latter.

Feel free to use it or if you want different background and lighting let's discuss how and I'll set it up for you

12 min. At 400 degrees in home oven. Still lead showing with rub test.
Maybe a bad batch?

My impression, alloy and coating has not reached correct temperature, and possibly not in oven long enough. That Yellow colour is similar to Yellow Gold not Bronze, which is more brownish.

Ok everyone.. Did 20 min.and looks great. Had couple that when I rubbed 20 to 30 sec very little shiny lead showed. Some didn't show at all.

I'll ask the pros but I think I have it. Doing 2nd coat just waiting on it to dry. Couple pics of the first coating.

Thanks for update.
Your oven seems most probable with your failures. The last picture with coated baked alloy, you had light Yellow coloured coated alloy and also more Bronze (darker coloured) alloy.
This is telling me that you have inadequate heat circulation inside oven, and this is resulting in hot spots which over bake and colder spots which under bake.
You probably got failure with the under baked coating, and passes with correct darker shaded baked alloy.

Second coat.

All passed wipe test except 2 have very little that showed lead. I didn't take a pic as it would not show on the camera. All passed smash test except 2.
