thin areas on bike frame using metallic

[datadawg]

HELP !!!!!!!! I just shot a motorcycle frame for my first customer and even though I looked over the frame really well before putting it in the oven I have several areas that are thin or have no powder at all. The powder is champagne metallic that I bought directly from Tiger as Caswell didn't carry it.

Can I touch up the areas without messing up the rest of the frame? I am not sure if I have enough powder left to reshoot the whole thing, nor do I have the time to take the frame back down to bare metal.

I tired to color sand a test piece that I shoot two coats onto and it didn't turn out well as a shade difference was noticable at the edge of the two coats.

Thanks in advance for any help.

Boy, thats a tough one to fix. Your best bet is to have some powder overnighted to you and put on an entire second coat. The metallic in the powder makes it almost impossible to spot repair, in my experience. Depending on the gun used, I have found that I have better experience shooting a second coat "hot". I powder coat a lot of bicycles:

and so work with stuff thats sort of similar to what you are doing, etc.

That's a common tough area. You get the Faraday effect in tight area's like that and powder does not get attracted. Things with tough area's like that, I shoot hot, and no voltage. Just no voltage for those tight area's. Shooting hot will allow the powder to melt on contact, and you can see how much is being applied. Then, once all the corner/tight spots are done, you can turn on the juice and spray the whole thing. Just allways remember to do the hard area's first, and the easy one's last. That way you lessen the chance of over applying in the easy to coat area's.

Also remember that when shooting a second coat, it has to be a complete coverage coat. If you just try to coverup the areas you missed the old and new coated areas will not blend.

Lower the voltage, and shoot complete coat and it'll be fine.
