I'm about to use paraffin. Recommended by a friend. It should also leak test it. I need to put taps in first though  :) I saw a recommendation for a Loctite thread sealant but can't remember where. Any suggestions?

Seem to recall a thread which mentioned loctite and mentioned I think 3 grades each in a different colour. Was it green, yellow and red?

Yes, these are the different strengths, but I think that there is another one for sealing rather than holding threads. I've checked the loctite site and they have, I think, purple for this purpose but I'm not sure about its petrol/ethanol resistant properties.

It's yellow Loctite 577 for thread sealing. Just used some. Will leak test next week.

So far, I've had no problems with the tank on my A65, but that's possibly because of the low mileage the bike has seen - only around eleven thousand.

Believing that it needed a clean when I bought it, I used the products supplied by Tank Care Products, but refrained from going so far as to apply their sealant in case something else arose and I needed to clean it again. An awful lot of muck came out, and a couple of after-flushes of petrol got rid of the residues. It's stayed clean almost a year now with no protection, and there's still no blockages or build-up of sediments or rust that I can determine. Give Tank Care Products a try, but do follow their instructions to the letter.
