I need to clean, prep, and paint the lower crankcase of my 360. What steps did you guys take and what products did you use. I would prefer to rattle can it if possible. Also is a high heat clear necessary after the base coat? Thanks
Media blasting is absolutely best, but if you don’t have access to one, I got mine very clean with green Scotch-brite pads, a stiff bristle brush, simple green, and brake cleaner. No clear coat - nobody makes a high heat one anymore, and regular ones will yellow with the heat. VHT Universal Aluminum is the color I went with, it looks good.
- Scrub all the crap off
- Apply Metal Prep & Etch - I use the blue stuff from Home Depot, and rinse at the end
- Dry quickly
- 1 dust coat of VHT engine primer
- 1-2 solid coats of engine primer
- 2 light coats of engine paint
- 2-4 additional solid coats of engine paint
Of course, follow the instructions on the can to the letter. If I remember correctly, it’s 10 minutes between primer coats and 30 minutes to apply paint, then 10 minutes between paint coats and all coats applied within an hour.
Go to my post on nighthawk update. I just sanded my covers, then steel wool and scotch brite. I used dupli color engine paint. Did what it said per instructions. They seem to be durable. Just painted my engine Sunday and it looks great.
