• The seal at the base of my windscreen had, at some point in the past, been folded in on itself in one 3" section. I have unfolded it but at either end of the fold the rubber has distorted into a small peak- which holds the seal off the screen, allowing a small amount of water to roll down the screen past the seal.

    How can I relax the seal so that it is sitting flat against the glass again?

  • You may be lucky, and the extrusion has a shape memory, that it will (slowly) relax back to.

    'Slowly' dependent upon available energy, UK late Winter, it will never warm up, till the Summer.

    Gentle heat, (probably not the heat guns recommended on here for paint removal), might speed up the process.

    Alternatively if the fold has been trapped 'for years' it may never return to its desired shape.
