    I have used a lot of Candy Apple Red mixed 125 ml / 20 gram and just used 2 coats.
    When using it at 100 ml / 20 grams with 2 coats I would end up with really thick coats, both mixes worked fine as long as I got the coats dry before baking.

    I use 230 ml accetone to 40 g powder. It's a bit thinner than reccomended but it makes the lube grooves easier to coat. I then use 22 ml pr 10 kg boolits.

    I’ve used a lot of Candy Apple and mostly use a mix 120ml to 20 grams 1st coat and 105ml to 20ml for 2nd coat. For both mixes I use around 30ml to 14kg. I still vary mixes and amounts depending on projectile type / size and ambient temperature. Lots of adjustments to find what works best for me.

    My candy apple red doesn't look like I would think it should look. That and gun metal both don't look like they shy they do. I like the other colors tho.

    I usually use 120ml acetone to 20g powder and do 2 coats for pistol and 3 coats for rifle or the 460 SW. TonyN the colour will vary depending on heat you cook them at and how long you cook them but as long as they are cooked correctly they are fine regardless of the colour variations, not 100% sure but I suspect some alloys of giving a different colour but I may have been drinking that day.

    I'm not sure whether it's my technique with the hitek, or whether the lee 356-125 rnfb is just a painful design to work with but I haven't had any success yet. I do suspect that I haven't left the newly coated boolits to dry off long enough before baking. Though the first batch I baked passed the wipe and smash test, but still leaded badly after 10rds.

    So I have a new MP mold on the way which is what I want to shoot and has no lube grooves, so is way more similar to the 145gr jwords I've been using. I've also added the pid to my boolit oven, bought a .358 sizer to try and am investigating making a bigger expander/powder plug for the dillon.

    Also does anyone know if making new colours at home is as simple as blending 2 different hitek powders ?

    Blending is what I do best.
    Blend away.
    15gms of red254 and 5gm Gold 1935 makes Candy Apple like colour.
    If you are getting leading, try a larger dia. or a slower powder.
    AP-50 will lead with some bullets, where AP-70 will not...go figure..
    Hooroo.

    Everything I've loaded thus far has been ap70. 4.0 gr of ap70 with 125gr is about minimum to make pf and it leads up something fierce. I do have some ap50 laying around but haven't used it yet.

    Anyone have a picture of The candy apple red and Kryptonite green? Mine turn our beautiful but I don't know if I see candy apple red in mine. I bake 400 F for 10 min. I would post a pic but some reason it always says file to large.

    2nd image is pretty much same colour just different light / flash. Lighting conditions change the look dramatically.

    I see that Dark green metallic changed in color with the newest batch I have now. Its darker and isnt as glossy.

    The Black K15 sticks some to the tray. Should I add more acetone to the mix? I'm at 100ml/20 grams right now.

    You may be using too much or dumping out a little early

    When I got my last batch of the k15 Donnie sent a note with it that the standard ratio of 20gr to 100ml was far too thick and recommended using 8-10 gr to 100ml. I have had my best results using 10g K15 powder to 150ml acetone.

    I use the K15 Black to cover bullets use to test new coloured coatings.
    Mix it 20gms:100mls. 2 coats covers really well.
    These bullets get 4 actual coats and perform perfectly.

    The easiest way to clean coating from trays used for coating only is to soak them in a tray of acetone for 5 minutes and them wipe with cloth etc. Or scrap with a razor blade and them wipe with Acetone on a cloth.
    Hooroo.

    What containers do you guys use to mix the acetone and powder together?

    I've been using cheap Kmart plastic lunch containers with 4 clasps that are water tight but the rubber o ring seal gets hard after a while.

    I have to buy something else tonight.

    Got a welder, welded a 12mm post in place of the 6mm post and it has been good for 6 or so hours of run time. I love spending $600 to save buying a $40 part to get free bullets.

    At least this time my wife didn't see it.

    I use old glass jars, the seal does get soft and puffy over time, but then i just ditch it. It allows me to put a syringe in and suck up the liquid easily.

    I have used old PET bottles from coke or pepsi, they handle the acetone pretty well, but hard to suck up measured amounts of Hi-Tek liquid. The odd thing is, they bottle did shrink somewhat.... Not a lot, but you do notice it. Others have bought a bottle of acetone from Bunnings and used this to mix it in, chemical proof and it seals.... Drop a few old projectiles in it to assist with mixing when you shake it up. Yet the same issue exists, getting the measured liquid out. I have just poured a little into a container to suck up from then re-fill as required. Do it in little batches as you want to keep mixing the liquid hi-tek, especially if a metalic is used.

    Think of the welder purchase as an investment, you will be able to weld all those things the wife wanted you to, so you really did buy it for her
