Upthread I mentioned that my frame was replaced under guarantee, that was because Dawes didn't tighten the BB sufficiently when they built the bike, so after two weeks and 150m it worked loose and chewed all the threads ot of the frame.
When the time came to replace the BB I found that the LBS had glued it in with what I took to be threadlock, but it looked a bit like Isopon body filler, and as they hadn't used any grease, the threads were badly rusted. Having spent hours carefully cleaning out the compound and rust, the threads were quite badly eroded so I wasn't optimistic, but after I treated it to lashings of grease the new BB withstood full torque without stripping.
Then I had a choice: risk wearing out what was left of the threads by repeatedly removing it to inspect it, or leave it alone and hope the grease would do the job. I did the latter for ages, but then curiosity got the better of me and I removed it for no good reason. The grease hadn't dried out, but it hadn't stopped the rust either, and what came out was a load of both, it was a bit like a mixture of olive oil and breadcrumbs.
Anyhow, that was it, by the time I cleaned it up and reassembled it the thread stripped, so it's had a threadless BB in since then. I should have just left it alone until the BB wore out.
