Larry,

I apologise for not explaining myself properly. What I was really trying to get across is the difference between waxoil, designed to spray onto the under side of a car, and cavity wax designed for inside chassis members and box sections.
Some time ago I worked on a car that had huge quantities of waxoil sprayed into the bottom of it's doors.
I was able to lift it out in one solid lump. So all it was really doing is weighing the car down.
Cavity wax is so much thinner than waxoil, if you did spay too much into a door or chassis member, it would just run out of the drain hole like engine oil. But unlike engine oil, it will leave waxy waterproof coating that will last a long time with water running over it, and 25 years + without water running over it.
Waxoil on the other hand, is thick enough to block drain holes. Before I learned about cavity wax, I used to put the waxoil container into a vessel of boiling water to thin it's viscosity.

I dont feel it is necessary to coat the under side of car with waxoil if it is well painted with some kind of rubberised paint. I would only spray waxoil under there if it was a scruffy car with areas of the rubberised paint peeling off and rust showing on the bottom of the petrol tank, etc. I often spray waxoil onto Japanese cars sumps (oil pan). Here in the UK it is very common for Jap cars to have oil pans rust right through from the outside in, because they never leak any oil!

I have not sprayed the underside of my Pantera with waxoil and never will. Cars rust from the inside out. That's why I am an avid cavity waxer.

If anyone is considering the ghastly job of stripping the underside of there Pantera back to bare metal and repainting it. I would be happy to start a new thread and tell you best methods, and the correct paints to use.
