simple Hi-Tek coating

[slide]

I have mixed candy apple red and the dark blue which made a purple like that until I baked it, and it went dark like the dark blue. Did you stir the powder before getting your amount out of the jar?

Messed up some way.

Don't worry about the hollow point OR the lube groove. You want the BEARING surfaces covered. Nothing else matters.

Getting bare spots on the serfice that's gunna touch the berral too

Also having problems with some sticking together after baking pulling them apart pulls the coating the off

Your coating way to thick if you have any sticking together. Remember this ISN'T Harbor Freight powder coating...

How do you tell if first coat is dry before baking

As mentioned, sounds like you are coating too thick. I'd suggest that you thin your mix with a little more acetone.

I coat mine very thinly and the acetone flashes off pretty quickly. I put them under a box fan to dry and usually within 10 minutes mine are ready to cook. I am doing mine inside my workshop which is pretty climate controlled. Not sure what temperature your building is and that could make a difference. I also sit a tray of uncooked boolits on top of my toaster oven for 12-15 minutes to preheat before putting them in oven.

After initial coating, i put in a wire basket to dry. Every 3-5 min i shake the basket to move surfaces around, i do this 3 times before exposing to anything but room temp. Then i bake. You should be able to touch and pickup any boolit without any feeling of tackiness

The preheat may be the problem, stop it and see if it gives better results

I set mine on top of the oven so the heat helps dry I live in Minnesota so it's not that hot here yet. After the first thin coat is it ok to put the second one on thicker

My limited experience says not too. Thin coats, usually 3 seems to lead to better success. Minnesota is having similar weather to Michigan, i find the acetone actually flashes off faster on the cool, drier days.

I'm assuming that you are cooking between each coat?

[fivel_976]

Yeah I cook between each coat

Also hard to judge how much to use on the bullets

I have never heard of a blue in hi-tek coating. Where did you get this?

Preheating on the oven is a good thing! It's not recommended to set the bullet tray directly on the oven. use a spacer of some sort (I use an oven rack bent to match the ovens contour so it doesn't slide off when removing the tray of bullets) If the tray of bullets gets to hot to handle comfortably without gloves you need a thicker spacer.
uneven coating on bullets could be caused by mixing the solution to thick ( stay between 20 grams to 100grams through 130grams), to much coating to amount of bullets (6 ml to 5.5 lbs works well for the first coat) another possible culprit is not letting the new mix of coating sit for at least 30 minute to absorb the liquid.
the coating separates in the jar very quickly (especially the metallics) make sure the coating is well mixed immediately before applying to the bullets ( I like using a 20 mil syringe, Suck it full of solution, squirt it out then fill it again, then squirt out all but what you need then squirt the rest on your bullets.
Over agitation will cause lumpy / grainy bullets. 15-20 seconds then dump.( dumping wet bullets is not a bad thing)

Using you squirt bottle, only need 2 tablespoons, its a very very small amount. More of it will stick to walls of container than to boolits. In my findings it takes some very fast, vigorous shaking before the acetone evaporates.
