Helpful Expert Reply:
Both the Alpha Systems 1021 Self-Leveling Sealant for RVs - White - 10.3oz - Qty 1 # AL98KV and the Alpha Systems AlphaThane 5121 Self-Leveling Sealant for RVs - Gray - 9.8oz - Qty 1 # AL45KV are good for use on TPO roofing and will allow you to re-caulk your roof accessories for a water tight seal. The only difference between these two sealants is that the 5121 has a longer drying time which will allow you more time to get it exactly how you want. Also, the # AL45KV is gray while the AL98KV is white.
I do recommend removing any old sealant and cleaning the area with soapy water and letting it fully dry before applying the sealant to ensure a tight seal.
