OK - I checked out Wolfgangs lead, he's right, Dynamat and Ice sheild are practically the same thing. I can't seem to find POR 15 anywhere other than online. Can anyone steer me in the right direction? I have a bunch of things "in transit" for my car right now so I hope to be getting alot of this done, and a few decent drives in, before it gets too cold. Can someone help me with my top issue. I had my top repaired a few weeks back and with in hours of picking my car up there was a crack running from top-center down. I don't know if it was cracked during the repairs or from the top being too tight? It has been suggested that the center post may have been touching the glass inside the aluminum trim and the top was putting too much stress on the windsheild and therefore cracked at the pressue point? I have seen tops that look like you could bounce a quarter off of them, tight as a drum. My top doesn't seem too tight or overly snug and before I put new glass in there is there any suggestions as to avoiding this again? Thanks, Mickey
