What type of mastic & supplier

[Enoch]

Hi Axle, most people seem to use Sikaflex but it's quite dear. There is an alternative called Polyflex LM, it's a polyurethane adhesive / sealant, I used it on mine it's brilliant and half the price of Sikaflex. I bought mine on ebay - 2 tubes were about a tenner, half a dozen tubes will be more than enough for the whole car.
