Sifus....I'll be removing my dash in the near future for some refurbishing work and am planning to do up some sound dampening + proofing on the firewall n front floorpan while the dash is out. anybody can give some sound reviews for the above products? I'm personally more interested in either RAAMMAT and sikadamp cos they're the most sensibly priced. if anybody is selling it, also please do quote me. my car has ZERO sound dampening installed FYI...
