Hi, I'm new to powdercoating and I have a question regarding candy color powdercoating.  I understand that the candy is nothing more than a clear tint and that the base coat goes on first.  I've only done solid colors and know that prep is the key, including removing old powdercoating ect.  What are the procedures for doing candy colors if you have to put on the base coat first, do you bake the baseocoat and let cool then powder over the basecoat with the translucnent colors?  And do you bake for the same amount of time?  I'm just trying to understand that if we have to make sure the item we are powdercoating is free and clear of all paint, rust, old powdercoating how is the second coat going on without being affected by the already powdercoated base?

I'm going to post a video answer to this one as soon as I can figure out how to post it.  The short answer is to (1) bake the first coat fully (2) let the part cool and (3) coat the top coat. 

 

I know that goes against what several people post online but trust me, I will show you otherwise.

I want to expand on that last answer a little.

Many people say that you must coat the part while hot.  WRONG!!  You CAN coat it hot, but MUST.....I beg to differ.  When you powder coat a part hot, you are simply liquid painting at that point.  The powder can run and sag and build very heavily.  The powder will melt to the part as it hits it.  If you do this with a candy color, no matter how good you think you are, you will end up with shaded areas on the part.  The thickness will be all over the place and the finish will have darker areas in it.  With a good gun and an understanding as to how powder actually charges and works, any piece can be coated cold, even a re-coat or a top coat.  It takes a little more patience and some knowledge, but the final product will look much better.

 

Hope everyone has a great weekend!
