Thank you for the advice, everyone. Just to close the thread, I removed the tank with ease, degreased it, etched it and sloshed it with tank sealant (POR-15) which appears to have been successful. The dashboard bolts required considerable dexterity when refitting. Perseverance and foul language, it seems, are fine bedfellows.
