Does Waxoyl affect rubber components in any way? I had my suspicions on a couple of pipe ends, which, after using new pipe, the ends began to crack.

Also, how best to get behind the front air vent seals on the bulkhead, as I note this seems to be a rot spot. Tried going in from the hinge holes, but cannot go further than the upright. Is it an all dash of jobbie ?

I did find that by drilling a 20 mm hole on the inside of the base of the door pillar, I could get out a good inch of wet rusty mud properly, and for it to dry out. After easy waxolying the whole pillar from here, a 20mm blanking grommet works as a neat finish - plus I can clean it out in future.

After welding both front buklhead outriggers, I also opted for the holey approach, by putting two big 30mm holes into this almost sealed box - both ends on the underside. I learned this the hard way from the last landy that rotted due to a sweaty box !
