Ok, here's a small update. I went back and decided to add a turbo shield to my W900 along with heater hoses in this shot. I've got a few more under hood details for this one before I am through.
And here's the start to the Cat engine in the dozer. Not much to see, but a lot of yellow paint. lol. You can't really see it in this pic, but I painted the ex. yellow, then a semi gloss black. Sanded it back with fine paper till the yellow just started to show through and then hit it with some Tamiya rust from a detailing kit. It's looks too black in the pic, but it looks about right in person.
