what's the best way to cut sound deadener

if your going to lay out dynomat or silencer i just lay out my sheet where i want to put them press them into place and then use a razor knife and trim the accordingly. I do all of this befor i remove the backing of course. Then i remove the backing lay it out smooth and then use a heat gun and roller to smooth it out the rest of the way to get a good then fit. Forms better also when you heat it up.Mecp Certified

Double check advice with your Meter.

if you use the xtreme watch out for edges will cut the heck out of you...!

 I  agree a sharp razor or utlity knife works quite well you also get the ability to work with the material better around difficult shaped areas.....one love
