i have tried the 3 you mentioned but i now use plastic padding cavity wax loads better does not need applying as often and looks better when applied and is also cheaper to buy

i'm using dinitrol

For the underside I use waxoyl underbody shutz like this

Best applied as three coats with a shutz gun it certainly slows any rust down. For the interior of box sections Dinitrol 3125 is better than the thin waxoyl.

Thanks all, how many litres would i need for the underside? Also does anyone have a walkthru on how to do all the cavitys?
cheers
