Do not waste your time doing this repaint work with off the shelf rattle can products. There are a few paint suppliers around that can make custom rattle cans. What I mean is that they can mix catalyst and product, such as base with its catalyst or clear with its catalyst and fill a rattle can with it. What you must understand though, is that the pot life of many of these products is no more than 3 hours. That means you will have to have the surface all prepped and ready to shoot, get them to make the mix, fill the can and go straight home and apply it. I would even have my old clothes and a shoot suit on when I picked up the product so you were ready to shoot as soon as you get home.

If you live in a large city, look for automotive paint suppliers and call them to see if they can make custom aerosol cans. I expect that some of them will think you are crazy when you ask this question because it's not very common.

I realize as well as anyone that funds and resources can be limited. That said, a compressor and paint gun could be a very good investment. I made this investment over 30 years ago when I could have had the work done for less, but I have had use of the equipment for all this time. I just recently upgraded the equipment, but I still feel that it is a very good investment.

Good luck,
