Powder Coating...

I'm tired of rattle cans and want to start powder coating my boxes. I already have a small compressor that was used for an air brush, and a cheap toaster oven not used for cooking. Can I just order something like what Eastwood sells (http://www.eastwood.com/hotcoat-deluxe-powder-coat-kit.html) and go for it? Is there a steep learning curve, or anything I should know? Is this something that can be done in a basement or garage without making a huge mess?

Also- What's the best way to put clear powder coating over graphics? I bought some bake-on waterslides to try, is there a better way? I know screen printing would be best, but I'm not doing big volumes to justify the cost.

What kind of boxes?

As long as your metal boxes fit in the electric oven,I like to gently hang the part on a rack and then ease it in for baking, you should be good. I've done small motorcycle parts with great sucess and its no more of a mess than sanding a piece of wood & it cleans up easily with a vacuum. I got a Harbor freight gun and use their powder-the store's about 10 mins from the house- Eastwood is a great resource for powder & I'm sure their guns are higher quality but the little I do the HF gun is OK. Have fun, Brian

I went to HF yesterday. They didnt have a gun, but I picked up a regulator, filter, and some fittings for super cheap. I ordered the Hot Coat gun from Eastwood. I'm excited to try it - if I never use a rattle can again I'll die happy.

What steps do you use to prep the boxes?
