I was at Piper Plastics the other day and asked about how I can shine up different types of clear materials. Acrylic needs a quick smear of the glue used on acrylic. Just a very light thin smear, will react and start "melting" the surface. He said torch for polycarbinate. Very, very, careful cause too much and bubbles and burning will start happening :)

Hi,
I have used a small torch to feather the edges of clear acrylic,and
you have to use with care.Propane torch is an excelent choice, but as
I said ,use with small strokes, and feather the heat to the
material,takes alittle practice ,but may work for you well. HTH Hank
