After a friend bough his landrover from the same person who i purchased mine, we decieded to have both out chassis re waxoyled, after pressure washing to create a clean surface. on his defender large cunks of what seemed to be roofing felt were pealing off the chassis, turns out the b@+!!£d had put a 1mm steel patch on the chassis, glued that on, then covered that in roofing felt and then put a load of waxoil on top. After going round both cars with a screw driver prior to pressure washing we thought the chassis were solid but oh no, a new chassis is required for his defender, thankfully i got off lightly with just a small hole about the size of a golf ball in the drivers side chassis rail!
some people these days!
