[b]I see different types of weathering stripping to be used around attic access doors and cold Cellar Doors what are the better types to use if you can possibly post pics that would be great thank you[/b]

See pics. I'm working to address exterior gaps/holes to limit access for pests and increase energy efficiency. The attached pics are of an exterior spigot and an AC unit attachment. As you can see, there is an old, black, peeling putty-like seal around both. Neither are doing a great job. I think they may be black pro-grade "Great Stuff" - but I'm not sure. How can i fix? Remove the old? Add a new layer? Something else? My goal is to eliminate cracks/air/pests/etc., but also for something to look decent against white siding. **Thanks in advance to this forum for the insights. Always appreciated!** Th
