Years of rust proving removal?

dart gt said
Hello everyone.I pulled the motor out of my Scamp and decided to clean the engine bay up some.There is stuff like yellow glue and rust check all dryed up all over.I tried varsol and it wouldn't touch it.The paint is good under all this crap and don't want to ruin it.I tried lacquer thinner and seems to work but I was told it will soften the paint.Any suggestions on how to get this stuff off.Thanks

Try spraying the undercoating with kerosene or laying kerosene wetted rags on it (if surface is vertical). Let it soak and repeat daily until the undercoating starts to soften (usually in a few days). Then wipe off. This method worked for me with no paint damage. Caution though, do this in a well ventilated area with no opened flame heat sources like a wood stove, gas furnaces, etc.
