hello all. I am a newbie when it comes to metal finishing. I purchased a complete powdercoating kit, and a sand blast cabinet. I work on small parts for most of the guys in our club.
I had a problem with a wicked orange peel, but i think i fixed it (water in the line)
I am, however, having problems with blending colors. I tried blending a light blue to reflective silver fade. The reflective silver flowd out and coated nicely...the blue, however, stayed fairly "gritty." The blue on bare metal flows out nicely.
I have the same problem with clear. It will flow out on bare metal great and give it a nice "wet look." However, when i clear an already powdercoated piece it stays gritty and will not flow out. I tried turning up the heat a bit, but it burnt the clear. (Now I have to blast it all off and start over). I am using an infrared light as my curing source.
One other problem that I sometimes experience is in small corners or rounded concave corners, when the powder cures, it "pulls away" from the corners...almost like it shrinks and doesnt have enough powder to cover the area. i cant figure it out. it has done it with clear and with gloss black. I usually just put a coat or two more on, and recure it. The surfaces are cleaned with acetone, prebaked, and then wiped down again. I allow them to cool, then coat, and cure. I wont handle them until they cool off.
Any help you all can provide would be great.
And...does anyone have any pics of the Anodized Powdercoat colors? AKA...translucent colors.
