Powder Coat Predicament
Hi all,
I've hit my first snag with my 59 Apache build. After finding my paint colors, I took my paint pray out to my local powder coating operation a couple weeks ago. They use Prismatic powders and have a ton of chips on the wall to choose from. I found a REALLY close match that I checked in daylight, under LEDs, etc. It looked great. Flash forward to today. I went to pick up my chassis and wheels that had been powder coated in the color I picked. The the color is WAAAAAY different. They're not even in the same ballpark. The powder coating operation is claiming this variance is normal, but being Prismatic offers 6500 different colors I can't see how they would be this different. Hell, the wheels look noticeably different than the frame despite being done at the same time with the same color. I've called Prismatic but haven't heard back yet. I'm at a loss. I'll either need to strip everything and redo it, hoping the coating shop helps me out on the cost, or deal with it as is. They mentioned I could topcoat it with a different color, but I'm reading mixed reviews on that. Any tips or recommendations how to proceed? Any insight you guys can offer would really be appreciated. |

Re: Powder Coat Predicament
That is not good being so wildly different.
I too have heard too from a friend who worked for a powder coater for awhile. |

Re: Powder Coat Predicament
I do some small job powder coating for personal use and I have used Prismatic powders fairly exclusively...I have never had a huge difference in a sample chip and the powder.
The problem with coating a different color (over current color) to the part is twofold in my untrained opinion... 1. The underlying color will make the new topcoat color a different shade, even slightly...that is how you can get some different shades and effects. 2. The only time I have used a color over a color, usually when I use clear powder for clear coat...or when I do a candy color with silver flake as the first coat...the 2nd or 3rd color doesn't want to adhere to the first color as well...I usually use something call hot flocking where the part is heated and then powder coated...so it sticks to the hot part and melts immediately, but then still needs to be cured in an oven. I would ask the shop did they do anything to the part before powder coating it...just to make sure they didn't put another color under it for some reason which could change the shade. Unfortunately if it were me, I would want to strip it and start over with a different powder coater...or ask them to see the powder they used...it should have the prismatic # and color name on the bag or bottle the powder is stored in. Sorry this happened to you! Good luck. Last edited by roll_the_dice; 01-16-2021 at 12:15 AM. |

I'm at the point where I want to strip it as well, but it's a ton of work. Maybe a chemical dip is a cheaper option. Doing this all over again, I'll be $3500 into this. It's getting expensive. The powder used was all the same prismatic # according to the shop - From the sample I matched my paint sample with to the powder that went on the wheels to the powder that went on the frame. All three are different. The shop is claiming the thickness of the powder may be part of this variance. I'm no expert, but it seems unlikely. |

Re: Powder Coat Predicament
The company I used to work for we had our own powder coat shop to do our machine frames and out side work. What ever you do don't spray new powder over the current powder. As said above it won't turn out well. Sand blasting will take awhile because the powder is plastic and the sand kind of bounces off the powder.
I know you picked out a color you like but the best powder colors are the ones the they spray everyday. If a customer came to us with a "custom" color typically referred to a "RAL" number we always did a spray out card and sent it to the customer. Not just sample card from the powder supplier. |

Re: Powder Coat Predicament
Have you paid them yet? I’d make him strip it and redo it I personally have never been a fan of powder especially when you put on bare metal it’s impossible to touch up and if you live in a moist area and you get a chip there is nothing to stop the rust Creep! My thought is they used the wrong color if the manufacturer sent the wrong color then they should be responsible . I wouldn’t do anything until you’ve talk to the manufacturer, I have heard that it can be stripped in a burn off oven ???

Re: Powder Coat Predicament
The spray out card might have ,had a undercoat/primer on it before thy sprayed that color on it. and you are stating your parts don't. No primer coat?

Re: Powder Coat Predicament
I believe it isn’t any different than paint, one drop off when mixing it it’s not going to match. As far as the parts being different that could be because it wasn’t thoroughly mixed especially if the shop received it in more than one container. When I painted my truck I bought two gallons so I batched them to ensure they were the same. Hopefully they will work with you

Re: Powder Coat Predicament
I can check with my powder coat guy I used to work with and ask him what is best practice for getting the color you want. Doesn't help the current problem but may help going forward. Also I will ask about a primer coat of powder before the top coat. I've never heard of that before.

Re: Powder Coat Predicament
I've never done a primer coat of powder. I go straight from sand blasting and cleaning the piece to the color powder I am using. The only time I have used multiple colors was on some brake calipers that was a candy red color. It had a silver base coat, then the red tint coat and finally a clear coat, but never a primer coat.

It could be guy spraying grabbed the wrong color and they sprayed it. The spray out not baked long enough to flow out. ? A screw up in the formula when mixed to spray, if not a premixed powder color. |

Re: Powder Coat Predicament
Okay, so I feel your pain. But devil's advocate.
You will never see the wheels and frame at the same time and with the same lighting. If your need to find a compromise, you could focus on getting the wheels right. |

Re: Powder Coat Predicament
My .02 is they sprayed the wrong color. You can be off by one RAL number and the powder once cured will look quite different.

Re: Powder Coat Predicament
I've sent my paint sprayout to Prismatic to color match. I'll get a pound of powder and have them to a test spray-out. I plan to compare from there and make a decision.
The bed of the truck will lif up to expose the air management as well as the fuel tank and batteries, so I'll be seeing the chassis regularly. My guts says we're stripping it and starting all over. |

Re: Powder Coat Predicament
I think you have answered your own question. You are not happy with it and wont be until it is corrected. It is a lot easier to accomplish that now than after its completed. You will look at it for years and always know its not 100% the way you wanted it.
It is a tough call and an expense but unfortunately and ultimately I think it is best for your future sanity to bite the bullet now. All that said it does seem to have a lot of flake in it so the color is different at the different angles. Your wheels for example look like different shades depending on the photo you look at. Somebody with experience in powder can probably answer but I know paint can be tricky depending on the angle, distance and ect on how it is sprayed. This one may be a tough one to get exact? good luck and it will be awesome when complete. Dave
