Loctite spray can insulating foam at Lowe’s $2.69

This foam is better than Great Stuff for several reasons:
1. UV resistance
2. Filling gaps without voids
3. Denser when cured
4. Ability to apply at lower temperature
Downsides are few:
1. Thicker straw that makes difficult to apply in small gaps
2. 12oz. can vs GS 16 oz. but I think volume of foam is similar
