depending on the state your living in you may not be able to buy the good old high quality paint remover.
I really liked the old klean strip auto/ aircraft stripper. I'm now stuck with the less aggressive stripper. it still works but there are a few must does to make it work. the 1st is to take some 36 grit and run it over the finish to put some deep scratches in it.
2nd is to apply a good heavy coat and then cover it with plastic sheeting. I just use the same plastic over spray sheeting we use for coving the cars when painting.
to remove the finish most of the time I will use a long handle razor blade holder and always new blades. not to dig the edge of the blade into the metal I will take a piece of sand paper and round the corners off the blade.
you have to let the product sit on the finish. they say let sit for 45 minutes but some times it will take an hour or two. again make sure you have enough stripper on the finish so the stripper doesn't dry.

if your dealing with some finishes like lacquer or an enamel with out a hardener AKA NON 2K product. many time the finish will not wrinkle it will just turn to a kind of liquid mess.
Sometimes when I need to strip a non 2K finish I will use the old type old DA sander lock into it's grind mode and with some 80 grit just start machine stripping the finish.
