It's up to the age of the vehicle. In my previous car washer under injector start genly leaking and under heavy acceleration sprayed fuel on the engine. Regarding the fibre glass. Automotive matts are made of butyl or other chemical stuff because of the many varies reasons. If it would be helthy / safe I presume many manfacturers would do cheaper option rather than asphalt based matts or the best and most expensive butyl rubber. Try to think why no one use fibre glass in other than stattic places when once fitted are never moved again? Why builders fitting fibre glass with gloves and mask on the face ? The answer is because it's not healthy to inhale it's pieces to the lungs. I wouldn't buy a car with fibre glass fitted under carpet or even worse under speaker / Subwoofer (SIC!!!) Would you??

Mmm do you really think materials used in building applications would be oil and petrol proof? It may by not flammable it self bu what about it with any flammable liquid? At home you don't have long lasting high heat. What is the temperature range of it? Last question: Could you show me just one of these stuff which gets placed around gas and oil boilers with just GOOD sound deadening properties?

First of all it nearly half price (£66 vs £103). To cut the shape all you need is scissors or a sharp knife :) The rest of it you might stick to arches to make car more comfortable and get less road noise inside. you don't have to cut the shapes as showed on the below link just trimm the corners. All you have to do is clean surface stick sound deadening and cut the shape of the bonnet not cut it into pieces. http://kereta.info/wp-content/uploads/2 ... oofing.jpg http://dynamat.com/products_automotive_hoodliner.html Don't use any foam used for architectural applications as it's not water, heat, benzin, oil, and the most important FIRE proof. If it will absorb water or any oil related liquids than it may set the car on fire. Car sound proofing materials are heat resistant. I work with it some time ago and saw what creative people may do... sometimes hardly saved their lifes.

why you didn't try better and cheaper solution? http://cgi.ebay.co.uk/Sound-proofing-de ... 861wt_1137 (£66 incl postage) or http://www.dynamatdirect.co.uk/dynamat-hoodliner.html (£79.99 + P&p)
