Errr,
that's the whole point, isn't it?
Underseal which dries tend to be brittle, with cracks forming and corrosion occurring beneath the hardened 'crust'.
Rather like 2 pack paint which has been applied with inadequate preparation, come to think of it.

Waxoyl underseal which is what you are using doesn't dry. I've used it and don't like it for that reason.
Yes, but you get covered in the stuff whenever you crawl under the car to sort out summat. Perhaps if it formed a skin I might like it more.
Sean, you are right about the old fashioned pitch/sand stuff. I don't like that either. It made a nice cosy jacket for the rust mites to beaver away under it.
Perhaps that paint system that they have used on the iron ribs of the Cutty Sark might be the answer. Supposed to last 50 years. Oh yeah, I bet it doesn't and I expect it costs a fortune.
