  • 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.

  • If the frame is smooth and flat you’ll be able to get a prefect edge & wipe off the excess from the frame using silicone tools

  • Can't you just use masking tape or am I missing something?
