  • I need a release agent for silicone that i can accurately brush onto painted metal windows.
    Am thinking vaseline but need to thin it slightly but not with a solvent that will attack the metal paint (dulux metalshield)
    Will be using colour matched silicone to fill the gaps on large crittall opening frames that are distorted so the gaps can be 5mm tapering down to .5mm so not something I can do with conventional rubber strips.

    Did wonder if silicone spray stops silicone adhesion? you can use cling film but its a faff and wrinkles making a poor seal.

  • No, for 2 reasons, in places the paint is fragile, no idea why as the correct primer adhered well and I used the correct dulux thinner, some days were hot some cooler which may have something to do with it.
    So bit fucked off after all the effort it took to strip/prime/paint.
    So masking tape will look shit and likely pull paint off in places
    So I want to make a silicone bead to stop most of the draft enough to stop the secondary glazing bowing when we get gales, the wind even lifted a 1.25x1.8m panel out of its track one stormy night and I nearly shat my pants.

    The gaps are not small,
