No seriously, the black brush on stuff is jolly good. My car had nothing else on the underside for 30 odd years (i.e. on bare steel) and it only rusted when the coating started coming away - it does eventually dry out and fall off if not re-coated. I agree with Hedd though, paint then apply over the top. Then take a look underneath once a year or so and address any signs of failure.
Check you don't need to weld anything before you apply it rather than after!
Interesting your point regards to Silicone Sealant C KC, I've seen a car for sale, and it looks like it has blue sealant here there and everywhere, sorry to go off thread a little, but have you had a bad experience we should be aware of, I'd like to know please. I personally hate the stuff too, but if I'm looking at a car that has had loads, I'd love to know what your bad experience may have been. Other than it just looking wrong, and quite frankly in my experiences, if you use a decent old fashioned suitable paper or cork gasket... it seals ok.
On the wax oil question, I'd agree. Its a good product, clean things down first a little if you can, it certainly helps to repel water etc.... I've seen bad experiences with cars that had Ziebart on over the years, where the parts missed had became like an anode on a boat, but that was some years ago...
