Get'n ready to install my windshield and rear glass, urethane sealed. I need to run a glass support/sealer dam for clean edges but not sure on brands/density they supply. 1/4x1/4 may be ok depending on any 'squat' it does from weight and contour. Or, would 3/16x3/16 be a better choice. Again, density comes into play. The goal is more for just clean/straight sealer lines since the glass depth isn't too hard to control, but I don't want the support dam to hold the glass too far off/up..
Anyone have any real world brand experiences. And butyl is not an option fr sealer or a dam material..
