Any way you strip is expensive. Paper can run you around a 1.50 a sheet, chemicals 40 to 80 bucks a gallon. With paper you can hollow out any filler, damage soft parts like pot metal. Chemical will do the same on filler. it the only way to go the soft parts but can damage plastics or fiberglass. Paper creates dust, chemicals leave sloppy piles of slime that needs to be taken off by hand or presser washer. causes skin burns if you get it on you. Dust will give you repository problems. It's all a matter of personal preferences. Each has its good points. Chemical works best on complicated pieces with sharp edges or compound curves tight, spots. But may need more then one application. Paper works best on large fairly flat panels but care needs to be taken not to generate to much heat as you can warp panels, grind off sharp edges.
chemical is sloppy messy in a nasty way in a small shops. Ok if you have a wash bay to do your wash in. You need to kill the chemical with water which gives you a flash rust on bar metal and it runs into voids cracks and open places you can't get into to paint. But the expense stuff will cut threw heavy layers but works best on enamels. Once you get on to using chemical striped it will work for you but it will cost you to learn. Were paper is easier to do but if you use air or electric you can make mistakes fast with machines and takes a long time by hand.
