Hey Mike, thanks for reaching out!
The Alpha Systems AlphaThane 5121 Self-Leveling Sealant # AL35KV is designed for wood, metal, and glass materials. Since your skylights are polycarbonate I recommend using the Specialty Recreation Skylight Sealant # SR86RR instead because it is designed for polycarbonate skylights.
How many skylights are you needing to seal up?
