MG MGB Technical - Boot floor sealing?
|I normally post on the MGA section, but I have a problem with water ingress in the boot of an mgb roadster. I notice that there is a gap between the outer extensions at the back of the boot floor and the rear wing. Should there be some kind of seal there?|
|I believe some cars have a cork-like material to close most of the gap, with seam sealer to finish. Mine ('72 Roadster) seemed to have mostly gap and sealer when I stripped it down. When I got around to completing the boot I stuffed the gap with flattened rolled newspaper, laid a piece of polythene on top and then filled the resulting surface with seam sealer. Once this had almost set I removed the newspaper and polythene from underneath thus leaving a thick skin of sealer across the gap. It's a bit fiddly but if you make the newspaper section wide enough to grab from underneath it should all be pretty straightforward. There's still a dirt collecting volume underneath but at least no water gets into the boot and you can paint the sealant to finish.|
|Use foam strip, mastic etc. Water in MGB boots is usually getting in either around the fuel filler, through the cable grommets below the bumper , through the badge holes.|
|Many thanks for that guys! |
I suspected that gap should be filled, but could not find any reference to a seal anywhere.
