aircraft paint stripper. its like a gel. paint brushed it on and then used a scotch brite soaked with it. wear thick gloves cause that stuff is powerful. then rinsed with water and sprayed down with brake cleaner and then a coat of some silicone spray.
and its stock bottom end for now, i got a spare lly short block that spun a rod bearing but i think the crank is ok. im saving up and gona build it and have it ready for when i pop the stock motor.
