Im spending some time re doing the install on my Buick. I just wasnt happy with my results the first time around. One of the areas i wanted to address was my craptacular sound damping job. It wasnt horrible per se, but GM did nithing from the factory for the trunk, instead relied on sealing it off from the rest of the car. I didnt take that into account when i stuck a couple of 18's where the seat back once was.
Anyway, today i was rebuilding the trunk, and decided to use some lead sheeting on the back wheel wells, along with MLV on the trunk floor. I was floored at how easy it was. I spent more time waiting for the glue to set up sandwiching the lead with ccf than the entire job. It was like 10 minutes getting both sides finished. It molded its self perfectly to the curves, and a kick out on the bottom where it will meet the MLV on the floor. With no relief cuts, gluing this piece to that to bend around curves. Im pissed that i spent like 2 days cutting and cementing the "tub" when i did the interior floor. I could have finished it in a couple of hours using the lead.
Why is no one using the stuff anymore? It cant be the cost. The MLV cost me about $200 shipped to my door from Flaming River on amazon. The same 100sf in 1/64 in lead is $300 shipped from Roto Metals, again, off of amazon. If you are taking out your interior, and putting all this TIME money and effort into the endeavor, a 30% cost difference isnt shit, and the time and aggravation is WELL worth an extra $100. Your CLD and CCF costs are going to be the same. Not to mention its a HELL of a lot easier to move and handle 5 4x4x12in, 20lb boxes than a full roll of the vinyl. That alone makes it worth the extra dough.(keep in mind ive been doing this with a bad shoulder, so the full roll of MLV was a special kind of hell for me)
MLV still makes sense doing doors and large flat or gently curved panels, but i just cant justify using MLV for an entire project anymore.
