Caveats: Soprema did not produce this video and determines on a job-by-job basis the UV stability and water-tightness of the primer. Under Ideal conditions is maybe watertight and UV stabile for 6 months in the Northeast but that may not be true for Arizona or Souther California. We represent Soprema in the Upstate NY and can only speak to what we know about using Alsan RS in Upstate NY.
