Because I work on a large percentage of older vehicles I have way more experience with cruddy and rusty tanks than I wish I did .

The shaking with 'scrapers' inside is really important ~ shake until your arms are falling off then shake some more, I like to shake side to side as well as rotate .

It's a simple if arduous task .

I do Motocycle tanks too .

I work on a tight budget so I've never tried "Evapo Rust" , many Mechanics and Motocycle restorers I know tell me it's the shiznit because it works so well and won't damage the exterior paint .
