It worked ok on areas that realy need stripping but it has this characteristic of not being able to remove good sound underseal from sound, shiny metal. This is good realy, as I'm not trying to create more work than neeeded
I think I'll use ferrozinc and a coat of zinc/galv primer on the bare metal then reseal the floorpan with proper stoneguard - NEATLY

not like the git who did it last
Then...I can get to work on stripping the exsterior paint/s lol - I know theres factory paint job (caspian blue) a coat or red oxide, a respray of Crystal blue all to come off

but I will be doing that with paint stripper
pics coming...
