underseal/undercoatings???

hi guys, ive had the bottom of the car stripped, treated and painted and now its time to underseal it, my question really is what underseal do i use? i want a thick rubbery sealant that can be rolled on prefferably. (like used on the old audi's) . Any help is much appriciated. Thanks again.

If you have had it painted why not just cover it in a clear Waxoil type covering ? You could spray it on very cheaply .

easy chudd, yeah could do but i think because i will be driving it everyday and live in the dark depths of devon then with a thick coating of something it will put my mind at ease really that it is protected from all the sh*t down the lanes etc. ??
