You my freind have to much time on your hands...quality....dapper wrote:Ten minutes is no where near long enough. And if its just spinning at a constant speed, the gravel will do nothing but stick to the inside of the tank through centrifugal force. The way I did mine, was to bungy strap a bit of 4 x 2 across the mouth of a mate's old cement mixer. Then bungy strap the tank to the piece of wood. Tank had about a third full of spar (roof chippings) and left it on for an hour or so. The slow speed of the mixer, means the spar is being tossed around inside the tank. Job done.

Half a tank of these:
Strapped into this (belongs to a mate on this site ):
And left spinning slowly for most of the day at work, and even the rustiest tanks can be saved.
Also fits smallframe Vespa tanks as well

If not that bad inside then -Bicarb & white vinegar and stand well back!
Slosh out with white spirit a few times after too and then a once over with some petrol and 2stroke mix to coat it.
