Rust inside tank that hasn’t been used for a while
Discussion
I’m currently having a tank repaired that hasn’t been used for a couple of years, it has a light surface rust inside the tank.
I assumed this would just go away once it was being used and filled with petrol again.
However, the person who is fixing the tank has offered to remove it for £70 and add a zinc coating for £50 to stop it coming back again.
Do I need to do this or is it just an OCD thing?

I think he means like small fish tank gravel, not off your driveway... Would sand really be abraisive enough when given a light shake to clean that up?
Fill in the missing word xxxx paper
If you're going to use an aggregate to remove a layer of rust either cat litter and LOTS of agitation or a more aggressive granular substrate would be better. Something like 3mm sieved angular/crsuhed stone but not pebble shaped stone.
Alternatively, use POR-15 epoxy to seal and cover the rust in one go. Much easier...
I would try to clean this, all rust particles end up in the carbs/fuel system.
1 pound of small SPAX screws inside, close cap, fix it to some 2x2s tied to a cement mixer drum,
let it rotate for a few hrs, rust gone.
SPAX are sharp, and hardened, but not too big to cause dents.
I had that inside an ST70 tank.
SPAX added, no mixer at hand, did the rumba shakes for 30 minutes, and ended up clean.

Nice solution

Sand is a self compacting aggregate and only works on sandpaper because it's fixed in place to the paper, preventing it from moving and clumping effectively flattening the outer layer. You don't rub your feet raw running on the beach for the same reason.

If you run for miles or play with sand in your hands it rubs your finger prints off, keep going and they get red rawIf you're going to use an aggregate to remove a layer of rust either cat litter and LOTS of agitation or a more aggressive granular substrate would be better.

XXXX blasting
I'm a builder and have building and sharp sand to hand, no doubt other things will work too.
