heat/sound insulation comparison

[Henry Jay Hannigan]

---RALPH:
Thanks nfor your valued comments. It is a slow Sunday morning in
Vegas so I can Chat a little more.

The bucket of "lizard skin" I put on the FC was more expensive than
two sheets of the lead stuff at the Marine store..
two sheets about $210
one bucket about $250

I now regret I did not have a DB meter to test
the ..before ..and ..after sound..........but it sure seemed much
better to me in heat AND sound.....trouble with the FC, it seemed
like all the sound after applying the "lizard" seemed to come from
the front........NOT from the doghouse......
I truly believe application helped both....
One more thing...I see "lizard skin" sells a bucket of heat proof
stuff and a bucket of soundproof stuff.....ok to say stuff...no
need to sound fancey right?

Anyway, when I return from Australia next May, I am going to apply
BOTH buckets SOUND & HEAT...and I will try to do a db sound analysis
of BEFORE and AFTER ....then I will be able to report to the Forum
with actual on the job results...until then gang...all we can do
is..get along and talk about it......
Anyone want to come to Australia? We have a small house and are
willing to talk with any Forum member who wants to come to Melbourne
as we would be willing to put you all up for a week or so to get you
started on your tour..no charge....u can email me privately...we can
pick you up at the Melbourne airport..we live in a small town of
4000 people about 100 klicks from Melbourne...Australia is a must
place to see before going to the box!
