After researching multiple threads on here, I'm still undecided as to what to use to underseal my car! There seems to be contrasting opinions and pro's and con's for different products.

I'm looking for the best possible quality underseal I can get, I've not cleaned underneath yet but spent a while poking around, the underseal seems to be in good condition, can I just clean it up and add another layer?

Thanks in advance :D

It normally is mostly in perfect condition, and can certainly be cleaned back and patched up, as long as you do so with polyurethane stuff, and not that cheap bitumen based sh*te of the type sold by Halfords and the like.

How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Bitumen based schultz can't be painted, and in a few years will begin to lift, trapping water under it, reducing your underside to a pile of iron oxide in a very short time.
It's produced to help bridge dodging scrap claw their way through a couple more MOT tests.

Dave's already offered me the use of his compressor, I'll be taking him up on that methinks!

Have seen some products available in aerosol form but do you know if they apply as well?

I've ordered some Dynax s50 for the cavity's and Inside rear quarters, its what was used there during the rear end rebuild and is still there now looking fresh and rust free! :D
