Okay so I have been working on striping my JY 2.3 Turbo enging down and rebuildign it back up for about a month or so. I have all teh grease and grim removed from the block. I do have some stubborn spots of old paint that just doesnt want to come off. So does any one have any suggestions on how to remove the paint from the block? Chemicals elbow grease i would like to know.... Cause I just killed my Drill using a rotating brush
