Hello everyone,

Im looking to buy a powercoating gun to coat some of my auto parts and also some computer cases for custom builds.

Just wondering what a good brand of electrostatic guns or a powdercoating gun that can be used with a compressor that will have great results in the end.

This is the one im currently looking at: http://www.amazon.com/Eastwood-Hotco.../dp/B001KPEZSM

 

Thats the gun i have. It does the job. A good quality gun is going to run you 500 buck to thousands. The hotcoat guns have a hard time getting even coverage in hight corners compared to higher quality guns and doing multiple coats gets a little tough. But all in all its worth the money if you wan to do things such as valve covers and random brackets.

 

The Eastwood is decent. The best advice I can give on powder coating ECU lids (We powder coat our ECU lids here in house) is to make sure you have a good ground and good powder. A good ground will help the powder stick to all curves,etc. and the good powder will 'flow' evenly across the surface when 'baked'

 

Ok great, so it sounds like the Eastwood hotcoat gun is perfect for a beginner.

I do have another question though, When you are baking the powder it turns to liquid right? What is to stop the powder from running while it is baking? Or, is the powder when liquid thick enough to a point where it wont run. A computer case for example, would be completely vertical on the sides when being baked so it would be easy for it to run?

 

bake it flat Don't put it upright, but even then since the case/ lid is charged the powder will stick to it.

 

Well, my point was any way you put a computer case in the oven there will be vertical sides. But as long as i have a good ground and the powder sticks i shouldn't have a problem?

What if i did one side at a time using... lets say 4 bake sessions. Would the original coat be baked too much by the 4th session? I really dont know the limits to the powder or anything.. i guess ill find out soon enough though =P


Thanks for the help
