if your still trying to remove paint , and dont mind a little caustic fluid , brake fluid works well , if not go to a paint store look for a product called peel away it spreads like butter then you place special paper over it leave over night remove paper and most if not all the paint will come off.. as for the rust use an angle grinder , there is a product thats a gel can't think of the name off hand but it kind of eats the rust ( not the correct term) but it helps , then there is a spray oil called PB blaster used for freeing up rusted bolts ( was going to say nuts but i can hear you ladies right now lol) DO NOT USE THE PB BLASTER IF YOU DO NOT HAVE ALL THE STRIPPER/BRAKE FLUID THOUROUGHLY REMOVED, A CHEMICAL REACTION COULD START AN INVISIBLE FLAME !!!!!!!!!!!!!
