I just got my car's window tint installed and the installer suggested I get what he said was ASWF Dimension IRP 30. The problem is that when I went to the manufacture's website, the DImension IRP does not come in 30. I even received a manufacture's warranty card from the installer with the tint name, lot number, and everything. I'm just worried that I'm not getting the tint that I paid for since that tint does not come in 30. Thank you for your help!
