RE: Undercoating?

I've got a spot on my split-roof house that needs roofing cement every year.
The last couple of years I've used spray-on rubberized undercoating. I get
better penetration and I think better sealing than with the old quart can of
roofing cement smeared on with a putty knife.

In England a handy 'builders tip' is to use car underseal on a house/shed
roof.
