Wheel powder coat question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

chipflyer · 04-13-2006, 12:37 PM

I have a set of 15x8 rallys that I want to blast and have powder coated and was wondering how much powder it will take to do the job? I have a buddy with a new powder coat gun and an oven but we are not sure of just how much powder to order.

Anybody else out there ever do this or have an idea?

Thanks

jeff

I WOULD THINK ABOUT 2lbs SHOULD DO IT FOR YOU. YOU MIGHT HAVE SOME LEFT OVER, BUT SAFE THEN SOORY.

I just had this done and have a bit to add. Clean the groove where the wheel center and rim meet real well with some kind of solvent. There was grease or something in mine and it bubbled the powder coat when it was baked.

Hey there, I've been powdercoating for 5-6 yrs, and know some tricks. Cleaning that groove is a great idea. You want to really soak the wheels in solvent after blasting, then bake the wheels at a little higher temp than you would powdercoat them (450 is good). this helps to burn out any oils in the metal. Then give them another quick blast and and solvent bath. You may even want to prebake them more than once if you think it's necessary. Also make sure that you put on a coat of zinc primer powder before the color. I do business with Tiger Drylac powdercoating co. (they are on the web) Their primer has a very high zinc content. They sell good stuff for a cheap price. Columbia Coatings (also on the web) is a good source too. I like to cheat and warm the part up to 150-200 degrees and then put on the primer. This allows it to stick as soon as it hits the metal and gel up. You also don't want the primer to fully cure so that the top coat will stick to it when final cured. Powdercoating is a tedious job, but like with most things, the more attention you pay to detail, the better your final product will be. Good luck!!
