Looking really good, Ambie. High quality work.
I'm doing a similar Prodex install on the inside right now with the same foam and same PL300 adhesive. Pretty sure one roll of Prodex is enough and I think I bought enough of the foam for the strips, but my guesstimate has really missed it on the PL300. Mine is around halfway done inside the shell now and I've used 7 tubes of that stuff. Does seem to do the job well and the cost isn't bad, but I definitely need to buy quite a few more tubes of it.
Keep up the good work.
cheers,
steve
