Thread: Under car rust proofing

That tectyl stuff was rubbish Micky. Used to dry out and crack and let the water in.

Yep. something that will stick, is water proof and flexible.

Not really sure wax stuff will withstand pressure gun, its not made for that.

When I got my landcruiser new I stripped it down. Blasted rust killer into the seams, and let that dry for a week with the heater going in the cabin. Then applied the cavity wax to the interior seams ( like in the doors and window frames, pillars etc)

Underseal for the chassis and exterior floor pan. Wax in the chassis box section till it was running out.

No sign of rust yet anywhere and its ten years old now.
