Powder Coating in a Spray Can
So, my daughter is in the management program at Sherwin Williams and we were brainstorming about paint products. (I know, I know, most people talk to their daughters about shoes and clothes, I talk to my daughter about paint!) I mentioned that taking furniture pieces to an auto body shop to be powdered coated was expensive and time consuming and that I wished somebody made an easier method of powder coating wire furniture.

Hypothetical Question: If you could buy powder coating in a do-it-yourself aerosol can, would you? And, how much would you be willing to pay for a can?

It is my understanding that powder coating applications require the use of an electrostatic charge, as well as heat curing, as in this video. Might be that powder coating is not a process that can be easily adapted to the use of a spray can?

It's a great
idea, in the abstract. But tchp is right -- powder coating is a process. Something in a can is going to be paint, regardless of the ingredients. I'm sure S-W could come up with something that looked and felt like powdercoating -- that impressive, slightly-waxy-feeling and sometimes rather thick coat. But would it be bonded to the metal (or whatever) in the same way ?

I've been told that wood can be powder-coated, by the way. I guess as long as a charge can be created ? Not sure about that.

Ahh, it
appears to be very complicated and not for the do-it-yourselfer. No wonder it looks so much better than regular paint. Maybe if you clip your chair to your car battery, rev her up and then spray w/paint? Or would you just electrocute yourself?

I think that the primary advantage of powder coating is that it allows the paint to be applied as a dry powder (held in place initially through static electricity), which enables you to apply a heavy, even coat without the material running, sagging, or dripping. Hence, it is popular for items that have very complex surfaces, like automotive wheels, bike frames, etc. Since most powder coatings are heat cured, the size of the item being painted is limited to the size of the curing oven that it can fit into.

Home powder coating is easy.
All you need is powder and a gun (and a few other inexpensive miscellaneous supplies) from Eastwood, a small air compressor, and an oven large enough for your parts.

Works great, lasts a long time.

fastfwd...
seems strangely like a fabricator to me...HERE!HERE! Eastwood is a great company for tooling/product for DIY individual...as per the original post....the best you could hope for in a can, in my opinion, is something that resembles powder coat...but taking it to a body shop will always take longer as they are usually a middle man....and where theres a middle man, theres a mark-up...see if you can find A] an independent sandblasting company and an independent powder-coater or B] a coater that has the means to do both......and of course, if you can, wait until you have multiple pieces that need the treatment, you can usually get a "group discount" with some finagling....
