Cleaning / coating inside of cross members and frame rails?
« on: August 15, 2019, 08:15:42 PM »
I'm curious if anyone has found an effective method for cleaning and coating the inside of the cross members under the floor pan and the rear frame rails. I also need to clean and coat the inside of the roof. The t-top leaked and there's some rust inside the roof needs conversion and coating to prevent it from coming back. Problem is the area is not very accessible.

I used a product from Eastwood, I think it may have been called internal frame coating, or something like that. It had a special nozzle and a long plastic tube that was attached. Then end of the tube had a nozzle that sprayed in a 360deg pattern. The tube was long enough to reach deep into the cavities. I dont know if the stuff works, if it did any good or what, but I figured that was the only to get in there and doing something was better than doing nothing.

As RK said, there's tube and pipe sprayers that fan out as you pull ot through. A coat of paint doesn't stop rust though.

The stuff that I used is supposed to be a 'rust converter', which I suppose is more than just paint. But I agree with AUS, again, I figured something was better than nothing.

The Eastwood internal frame coating comes in green and black.  Only the green is avalible at summit racing.  The coating has a phenolic resin in it, so it is a bit more than simple paint.  I have used it on the internal cavities of body components a good bit as I re assemble my shell.  It's pretty wet stuff, so it flows like water, but sprays nice using it with a standard spray nozzle or with the special straw.

Yes, some are better than others. Even a light surface rust coating can seal against heavier rust. I was more referring to rust issues where you know it's a big problem already and will continue eating away.

I was thinking either the phenolic or the wax coating for the cavities. But my first concern is that if the surfaces are covered with dirt and road crime that the coating will just fall off.

The green stuff is what I used, and yes it is very watery. If I could I hit the cavities with a blow gun until dust stopped. I suppose short of cutting things open that's the best you can do. Again, may not be perfect, but cant hurt either.
