Mapp isn't really even manufactured anymore...
MAPP gas - Wikipedia, the free encyclopedia

On 31 April 2008 the Petromont Varennes plant closed its methylacetylene/propadiene plant. They were the only North American plant making MAPP gas, and the only legal supplier of trademarked MAPP gas in the world. This caused a widescale shortage, and many substitutes were introduced by the companies who had repackaged the Dow and Varennes product(s). Most of these substitutes were propylene, like MAP//Pro [2] from BernzOmatic. Some were mixtures with higher hydrocarbons or with other ingredients like acetone. Many of these work acceptably in gas/air torches, but none work as well as MAPP in gas/oxygen torches.
