Eastwood Internal Frame Coating, Internal Longtitudinal Coating Options

[Highland]

Just wondering if anyone has used Eastwood's Internal Frame Coating with the long tube to spray inside the longtitudinals with the heater tubes still inside.

I'm just wondering how effective it will be with the heater tubes in the way. Eastwood says it won't damage the heater tubes, but I'm not sure of that if they are made of thick paper.

Opinions please.

I've used it on the frame of another car but not in the longs of a 914. I think it would work okay though. The product is basically a phenolic resin plastic paint that sets up solid and, as far as I can tell, odorless. Whatever soaks into the paper outer shell of the heater hose will set up once it cures and I doubt you would get any chemical infusion into the inner aluminum wall of the hose.

The supplied wand works pretty well to distribute the coating in internal members, but as you mentioned, the hoses and tubes are in the way. You would need to make two passes with the wand; one above the tubes and the other below, to get good coverage. Then a boroscope to check your work, I think.

My biggest beef with this product is that I can find no actual data on how well it works to stop or retard corrosion when applied over rusty surfaces. Eastwood's own description and claims are pretty vague. But I'm still planning on applying it in internal members of my car where I can't get into to clean and primer. But I just finished rebuilding my longs so those have a nice coat of epoxy. But I still plan to follow with cavity wax.(IMG:style_emoticons/default/biggrin.gif)
