| Post subject: | Sealing foam around rear seat and parcel shelf |
I'm in the process if painting the entirety of Susanna the 850, and to prep the interior I had to remove the foam that sealed between the rear seat frame and the rear side panel, I've also had to remove the same stuff from between the rear parcel shelf and the rearmost pillar. When I rebuild the car, I would like to reseal these areas, to keep the boot separated from the main interior, what would be the best way of doing it? Ideally I'd like to use something fireproof, after all, the petrol tank is in the boot Any suggestions Sikaflex? messy? |

Just get some foam from Clark rubber. I wouldn't be too worried about being fire retartdent, if the fuel tank goes up, sicaflex won't stop it. |

Fibreglass the side panel to the rear seat bulkhead, both sides. It's about an inch gap (or so?). Then Sikaflex the rear seat bulkhead to the boot floor. |

Expanding foam might work.... aesthetics wont be great though I don't advise it, just chucking up ideas |

Just stick the sponge back in the hole. If you are that worried about safety buy a car with 5 stars. |

I had a look around, almost all of the usual suspects make a fire resistant product, Sika, Bostik, 3M, Henkel/Locktite. Fire resistance isn't necessarily that important, but some products, like the original foam most likely are flammable by themselves It's surprising no one here has done it before, most classes of circuit racing would require it |

CAMS require a fireproof bulkhead between the interior and the fuel tank. But if the crash is that bad the fire comes in via the broken back window. |

My cooper look alike mini that was built for future use as an Nb car by the previous owner has the boot sealed from the passenger area. He made up aluminium plates that fit in the gaps. They are riveted to the seat back and parcel shelf. He then sikaflexed them to seal the remaining gap. For my other car I just asked the chick at Clark Rubber nicely and she gave me off cuts from their cut to size foam. Filled all the gaps like factory for zilch. M |

You use closed cell foam, won't let fumes in, and if it did, it would warn you that you have a problem in the fuel department........there shouldn't be petrol fumes in boot. |

There are heaps of fire rated expanding foams available these days. My Traveller just has the fuel tank in the back. It has a bit of vinyl covered cardboard between the fuel tank and the passengers. Tim |
