acrylic is awesome to work with!! (just make sure your working in a well-ventilated area when using the weld-on or youll go for a loop or two) i also 2nd the heat gun method , i put my heat gun on low and put it about 2 inches from the glass,,very slow process but works great.
also a hair dryer does work very well because you never have to worry about it getting to hott and bubbling the glass, it does however take longer but you want to take your time anyway!!
