Thoughts on Hood Insulation

Well, when I owned my 64 Belvedere I thought I had to replace the hood insulation as it was getting ratty. I bought the new insulation blanket and clips and put them on. What I noticed after that was everytime I opened the hood there was a layer of fiberous dust from the insulation laying on the aircleaner lid and inner fenders. It started to bug me that this dust might be getting sucked in to the aircleaner too, so I decided that any benefits from the insulation were being negated by the dust it was causing. I ripped it out and have never liked the insulation idea since. JMO, Geof
