Just had my TR7 DHC in for its annual test which it passed OK with no problems but the tester made an observation about some surface rust on the rear chassis members.
Its on top of the two chassis rails under the boot floor. They extend from the rear bulkhead back under the boot(trunk) floor where there is about a two inch gap between the top of the chassis and the floor. You can feel some surface rust on top of the chassis rails if you run your hand along them. Its not posible to see without a mirror.
Question is, how on earth do you deal with that? [?]

Remove the rear axle & the fuel tank, then there's plenty of room to get in there & sort it out. If it's only surface rust a good clean up then a couple of coats of hammerite should see you OK. Just re-done mine after 18 years & still in great condition. [:)]

Access is so much better once the fuel tank and rear axle are out of the way. You can actually get your head up there to see what needs doing AND do the remedial work without being a contortionist.

If you haven't had to replace your tank yet, you will in the near future as they rust from the inside out. [:0] You have to drop the rear axle to replace the tank, then there's lots of room to clean up those chassis legs.

Usually UKer's use Hammerite, N/Aer's use POR-15. I don't know about Hammerite but POR-15 is moisture activated, when is cures no solvent will touch it, the closest thing you can get to liquid powder coating. My above tank area was like new so I just waxoiled it (ProForm). While you have your tank out good time to seal it (use POR-15 kit or it will fail in future (why I had to do mine.) Tank is easy to take out (have it near empty helps) if you take out rear suspension. Good time to POR-15 rear axle and upper/lowers links. I hate doing just half a job.[8D]
