Removing Rust
So I'm trying to restore my dad's old Scwhinn Varsity. It's got loads of rust on the frame though and I don't want to spend a lot of money. What's the best way to simply remove rust (assuming there is one) while keeping the original paint job? Will I have to give it a "molasses bath" as i saw an earlier post say? And if so, could you tell me how to do it?
Much Obliged.
