:lol: yah, the block is bare right now, but ive never done a paint job, and the rust kinda concerened me. I dont want to paint it and then have the rust come through, even though its not a lot.
If you sand all the rust spot off, then clean the block with denature alcahol the rust will not come back. If you keep the block bare with out the paint to seal and protect it. Rust will come back.
