I use the entry level gun from Eastwood. I think they sell it for around $100 now. The oven I use is just a regular home one. It's actually my old oven from the kitchen that is now only use for PC. After a while I bought a silicone plug kit from Eastwood to make life easier filling holes and covering threads and such. For stuff thats need to be covered like the nipples on carbs I just use tin foil.
