Recently I purchased a Caswell Electroless Nickel Plating Kit. Electroless plating differs from traditional plating by eliminating the electrical current that is used in traditional plating techniques. With electroless plating you are basically mixing two chemicals and heating them to 180 degrees F, and then immersing your parts for about a half hour. All the parts I've plated have been bead blasted first, and then cleaned of any oil or contaminates. When you have depleted your plating solution, a neutralizing chemical is used to make the solution inert for proper disposal. I'm real impressed with how easy a process this is. I wish I had started using this earlier in my restoration because now I've been going back redoing parts that I had originally painted. Caswell sells a large variety of electroless and traditional plating products as well as powder coating, paints, coatings, buffing and polishing supplies on their website.
I have a bunch of different shape containers I use for plating. Ideally you want to use as little plating solution as possible. I prefer glass containers because you are heating the solution to near boiling, but I have a few plastic ones I use. I also have an assortment of silicone caps and plugs as well as hi-temp (powder coating) tape that I use for masking off areas I do not want to plate.
