The insulation blanket under my hood is looking discolored and an area over the battery is deteriorated due to acid I suppose. Has anyone come up with a good solution without spending the $185 I see they are asking,if indeed it is available?

I think the consensus is that the insulation is not needed. There should be absolutely no issues if you just remove it.
or
If you're not worried about 'pretty', I've 'fixed' several on other cars in the past with pretty good results. Home Depot or Lowes should carry aluminum tape (for duct work) that's easy to apply & holds up well. This is probably the only application where Duct Tape (the fiber kind) can't fix it. That stuff will break down & fall apart in the hot environment of the engine bay.
Here's a thread where it's discussed:

I think the only real advantage to having the liner was noise and vibration damping. My battery exploded a while back and it turned it into pudding and I haven't used it since. Without it, it's kinda nice hearing more of the S/C whine anyways. ;)
Dynamit would work well for heat and noise with no issues of stuff falling into the bay
Dynamat turns to soup when it gets too hot though. I would be careful with that. (heat gun is a Dynamat installers dream.) ;)Quote:

John, did you get the photo's I sent you?
Yes John, I did. Thanks. You said I could post them with my questions but you were not fully aware of my ineptitude on this machine.:o I really do have some redeeming qualities though....honest!

look at the spec's, their product spec's out just as well as the dynamat at half the cost. Get some extra and do both skins of your door's. Make alot of difference. I used almost also hundred foot of it so far.:)Quote:

You could easily use some lizardskin to block heat the same way and block noise as well. Obviously it won't fall off either. I have also seen sheets of aluminized insulation similar to what we have available from most auto parts stores. It would be attached in the same manner as our stock insulation.
