I got tired of being soaking wet and stopped short of really thoroughly cleaning the frame and crossmembers internally, applying pre-paint cleaner, went to the internal frame coating and it seemed to adhere very well. Eastwood makes a good product, have at it.

Get a couple more cans and get into the radiator crossmember and the other crossmembers along the frame, spare carrier. I believe Eastwood recommends two coats, I used one coat. A smart guy, not me, would mask over some of the frame openings to prevent drippage, I believe Eastwood recommends that also.

Eye/face/head protection, gloves, long sleeves/overalls is a must. That stuff is nasty to get off when it gets on your skin. The 360 degree spray head popped out of one of the frame holes and laid a stripe of it along the side of my face.

HINT: uncoil the spray hose and lay it out straight over a house furnace duct for a day until it loses the "coil" it wants to stay in. Much easier to slide it into the various frame openings. Best of luck to you.
