Combustible Engine Insulation (Soundown) Risky??
I just replaced my old (falling apart) engine box insulation with Soundown's "Peace and Quiet" kit. What comes in the kit is supposed to be "Acoustical Fire Retardant Foam." Looks great.
After I had all this installed, I took a scrap piece and tried to burn it with a lighter. To my surprise, after just a couple seconds of the lighter the foam was on fire. This stuff burns pretty well, had to blow it out. I have fireplace kindling that is harder to light than this foam. My old insulation didn't do this.
Now, how wise is it for me to be putting this foam, which is basically combustible / fuel for fire right next to my engine? The gap between the top of the engine and this insulation is about 3". Would seem to me that in this space, you wouldn't want ANYTHING that can burn as easily as this foam. Could an overheating engine (happened to me last year) ignite this foam? Am I being too paranoid?
