Very interesting thread.
Thank you all for the hard work. I will follow this thread closely.
Made some last night in .309 .379 and .460. Try them in 7 days.
I'm new to casting and still gathering materials and tools. I am certain I am going to start with PC or Epoxy coating and skip the lube. Thanks for all the great info!
Welcome!
There is tons of info on here. Take the time to read ALL the stickys......lots of info!
My standard is ESPC, but many are using dry coating. I have not been happy with the finish and evenness, but give it try and judge for yourself.
Again, welcome to the habit!

I just reported what I read. Lot's of people have opinions. I have them too.
But to comment on your opinion I do not think lead is going to wear out barrel unless you lead it up and get aggressive trying to get it clean. But 60-70,000 rounds may not be much of a test.
Tractor Supply has the applince spray epoxy less than $4.00,I have used on metals but not boolits,It may work?
It gets relatively hard .......eventually. I used Rustoleum and baked it 250F for 20 min. Still did not firm up for several days. If you are in no hurry, will probably work. For $4, try it. There is always a do-over in the casting pot!!!!!!
Check the can for any baking info. Most epoxys need to bake to form the molecular bonds.

I tried this, results for me were unsatisfactory. 1 coat applied per instructions on can, another coat a week later. every week i check them and I'm still not satisfied. I will remelt the bullets I tried.
It was on newly cast bullets. I could hammer them with a little flaking, but my fingernail took the coating off real easy each time I tested it over the weeks. They may eventually cure but this is not a system that I will enjoy doing long term, hoping the es gun will be what I need.
I wanted to thank you for thinking outside the box though. all these ideas, even the ones that don't work for me personally only serve to enrich our hobby and increase our options.
Dang, I ordered a can of the VHT epoxy paint for $8.99 from Amazon Prime (free shipping) yesterday and UPS just now beeped horn It was overnight expressed here to AZ, now that is service.
That looks good, thanks for your post. I will drill some hard wood boards for spraying the boolits. But I also have some pieces of aluminum plate, think I will drill one side for a certain size boolit, then flip over and drill the other side for another size. Then use the drilled aluminum plates for the baking thingy with the coated boolits standing upright to avoid sticking together and etc..
Keep in mind there are numerous types of the VHT brand of coatings. The ones that work pretty well for us are available from your local Auto Zone, Checker, etc. It is hi-temp engine epoxy and states on the can that a hi-temp bake is needed to form the bond. The bake can be either a real bake (which we do), or running the engine to temp for a period of time - which what the stuff was originally designed for.
Sounds like you may have a version of VHT that is not the hi-temp stuff. I have 2 cans of it. It will not get as hard and takes much longer to cure. Check out their website for all the info on the different variations they have.
The only one I have found here in the PHX auto stores is the gloss black. They do make a white according to their site. As I said above, it does eventually get hard after baking, but PC hardens in 10 minutes (when cool). No additional time required for curing/drying.
And VHT is extremely expensive as opposed to PC'ing.
Have fun coating!

The can I have is exactly the same as the one posted by OP, including 250 f on the front label. the calipers Most all the high temp stuff is not just epoxy, but contains ceramic. Most other epoxy coatings show temps as N/A.

I don't know what the temperature is like where you are using it... In cold weather it chipped and flaked for me. Baking or not didn't matter.
The can I got from the Amazon link earlier in the thread had no instructions about baking.
I did not bake the first batch. When they flaked I did another with baking. It was no better.
It does not hold up in cold temps.
Here on the forum we share our successes and failures alike on these new techniques. I have lots of both! This is really the only place to go that I know of with this vast knowledge available.....FOR FREE!
When people report on what works for them, I generally use it and save myself time, money, and frustration. If you wish to experiment around, feel free. Just please let us know what you find out if it differs from the many other reports.
have fun coating and shooting!

I just sized mine and the results of no bake were pretty iffy. Epoxy was cleaned off part of any band that was sized. I had one the mold wasnt fully closed on so was bigger. That one everything came out siver and shiny. I waited over two weeks for cure.
I still have my .379 adn .459 boolits to size, I'll bake those before. Give it a go..if it doesnt work I'll use the paint on auto parts like I'm suposed to.
