ive bought a valver spoiler, and some waterproof sealent/adhesive (is WHITE so needs to be under the spoiler and not on the edges... we sell clear bath sealant at work but it doesnt say it is an adhesive so didnt wana use it... would he clear sealant work? id rather use it than this white (but very strong!) stuff!
also, when i placed the spoiler on top of the boot, on the rubber bit, it doesnt line up right. so i can either position it so theres a gap on the roof side of the spoiler or a gap on the boot side of the spoiler (the two bits on either side that go down the side of the window slightly). surely i need to do the latter as if i have a gap on top the wind will tear it off???
