single layer is more efficient. but doing 2 layers works as well. when you layer vibraflex just make sure you "burn off" the plastic liner that is on the top of the material before you apply the second layer.

@@AntonJMiller great to know. BTW I saw on your site 225 out of stock. Any word when plan to be back in stock?

@@dtbrown1978 just got word the shipment is in Chicago. So hoping for next week or the week after.

@@AntonJMiller thanks! I live in Chicago. Too bad can't get locally. Lol

you dont "need" to torch it on no, it just goes faster with a torch. it simply needs to be hot to be applied so that the adhesive kick off good and also so it conforms easy. with extra heat after application you can also see any air bubbles which is critical to not have air bubbles especially when upside down.

@@AntonJMiller ok were do you get thos stuff it seams out of stock most places. How much for a 4 door tacoma just did a blowthru and roofs going crazy.

@@cristovalmontoya5222 yea I am out of stock till probably the end of the month or early May. I hope haha

@@AntonJMiller is it that much better than layers of like second skin or regular bitumen deadener.

@@cristovalmontoya5222 second skin is a great product and I would recomend using both this and second skin for best results.
