Hi,
Take a look at my thread, about half way down...this is what was done to the entire underside...
http://forum.earlybay.com/viewtopic.php?f=2&t=11057&start=220" onclick="window.open(this.href);return false;
I had the old underseal scraped off where it was loose, followed by a rust converter, which was also sprayed into all the chassis and box sections, bellypans etc, which then turned any rust into a stable form, and then encapsulated it, then followed by further coats of a 2 part epoxy paint in black, which has encapsulated the rust converter, this was done on the external metal
All the box sections, cavity's, doors, engine lid, tailgate etc were then treated with a cavity wax (still have 10lts left over!)
I have since had a further treatment, as i wanted a stone chip type finish, colour matched to body colour underneath, and it's just being finished off now. Another 2 part treatment with hardener, tintable to what ever colour you want, mines is of course Pearle White. It's UPOL Raptor Truck Bed Liner, it's resiliant, adds some sound deadening, covers well, and of course is body colour, just mix, shake and spray. Saves waiting for stone chip to go off, then trying to get paint to stick to the evaporating solvents.... :roll:
I'll get some pictures and details up on my gallery thread over the next few days.
Cheers,
Alistair
