candy over chrome?

[kg4mon]

I have just started in powder coating, just finished my oven two weeks ago. I have done a couple dozen parts, brackets, bike frame, fender wells, all been super wet black. No problems at all , they came out perfect. Now here is my question. I have a atv frame and chevy motor block that I want to do in lollipop blue. I have ordered the extreme chrome as a base. What is the procedure for doing the two coat system. I know I need to outgas the block. Do I spray the chrome on while the block is hot, and at what point do I put on the blue. I also have ordered a clear, Do I put that over the blue. I would appreciate all help. Thanks Rick

If I were you I'd spray the block wet black first, then the chrome then the candy. candies are tinted clears so you don't need to apply a clear over the candy. spraying a glossy dark color under the chrome powder will help with outgassing & appearance of the chrome coat. if you do do it this way cure the black about 3/4 cure, let cool & spray the chrome & fully cure, let it cool down & apply the candy & fully cure. your masking will most likely peel so when the it's cool you can re-apply the masking.

I reccomend you follow the same instruction in the sticky thread for extreme chrome with 1 difference: Use the lollipop blue instead of clearcoat.

Do I need to sand the black before the chrome goes on? I would think with black, chrome, then lollipop , that would fill alot of the casting in the block and make it quite a bit smoother. Thanks Rick

Another question can put the freeze out plugs in the block or should I leave them out? I wanted them the lollipop blue also. Everything in the block is stripped and has been hot tanked.

I'd coat them separate. Mask the hole in the block and the back and outer edges of the freeze plugs where they mate with the block. My thought is
if the plugs are a different metal than the block there may be some issues with them expanding at a different rate when heated.

Thanks for helping. I may have some more questions later when it's gets closer to time to do this. My chrome pc should be here today.

Well I put the super black first cured about 70% and let cool then done the extreme chrome, and then let cool to room temp. Getting ready to apply the clear on a valve cover to try the clear out. I had a brake lever off a atv that I'm trying the lollipop blue on. I didn't seem to have a problem with the chrome covering the part BUT the lollipop blue didn't seem to want to stay on. It was like the powder was trying to blow off. I know that I wasn't too close to the part. It was blowing off near the hanger where I had my ground clip. Is this normal? I think I may have put on too much powder trying to get it to stick because so far the part looks more like a purple than a blue.
