ehhhhh.....Ill stick to real paint stripper.
go to walmart and go to the dry wall puddy/paint/varnish/acetone...ect...ect... section and you can get a gallon of oaint stripper for like $8.00 (I think mine is in a yellow can ....I want to say the brand name is talstrip).
its light blue in color jelly like liquid.
the stuff stinks badly so I recommend having your garage door open and better yet having a fan on.....and it will sting when it touchs your skin so you need to wear rubber gloves.
but man oh man is it a much more convenient and faster method .
I didnt have to wait 24 hours or nothing.
in a matter of an hour or 2 the job was done. applied the stuff to my engine bay with a paint brush (wrinkles the paint in a matter of minutes) scrape it off, and apply a second coat and scrape it off and was basically done.
and yes using a heavy grit sand paper on the paint prior to applying a stripper will help in lifting the paint ALOT.
here is a couple of pictures from when I stripped my engine bay last year.
