[Buzz, do a search for palmetto phosphate and read some of the threads explaining how easy it is! And confused since you plan on doing large parts which needs both large container and solution. If you have a glass bead cabinet and can boil water you can do those small parts with ease.
I do have a cheap glass bead cabinet. Bought it at Harbor Freight. I'm just not sure I want to do the small parts ( throttle linkage, kick-down switch bracket and crank pulley) myself when I'll have to send out the large parts anyway (hood hinges and hood release) due to their size. I don't think even one of those big 30qt. turkey fryer pots would completely submerge the hood release. I know the company known as brakeboosters.com does grey phosphate coating. I just wish someone would tell me that they had work done by them with good results.
Buzz, what I did was send out the hood hinges (not springs) to Brakeboosters.com (Steve), but did all the small stuff myself. Cannot tell you how many times I've gotten that out (solution) to do something missed. Another issue involves the color as there is a dark phoshphate and a lighter version more of a dark gray and I used both for different parts for our restoration.
Never used the grille but read about that from Mike or someone several years ago. What I use is a simple cheap two burner electric hot plate that will not boil the liquid but keeps it in the 180 to 200 range which works well. And by the way Buzz, my glass bead cabinet came from Harbor Freight also. Cheap and works fine but spend some time sealing that rascal up and make sure you wear protective equipment especially for them lungs.
