I just had work done on my 3208 Cats - painted white (both injection pumps rebuilt). The mechanic painted all of the parts that he had off of the engine but none of the nicks/scratches that happened on the nuts and bolts when it was reassembled.
When shopping for my boat, I looked at some where the engine paint had been neglected and the engines had started to morph into rusty-looking hulks. They still ran but certainly didn't look like what I want mine to look like. Absent the recent work I had done, my engines and paint are in really good shape and I'd like to keep them that way.
I believe that paint on clean metal is the first line of defense against external rust/corrosion and goes a long way toward protecting the system. My question is how to make that happen? My first thought is just to use spray paint but I'm not sure that's the best way. Any tips from the group?
Also, anyone have any suggestions on what kind of paint to use and which paint will match Caterpillar white? I'm sure I can buy Cat brand paint from the dealer but I'm wondering if maybe there's something similar that is more easily available and just as durable.
