Overall winner: Loctite Surface Curing Silicone Adhesive, High Viscosity

Key Differences

Loctite (B00DIQ8GFO) is a high-viscosity surface-curing silicone noted for waterproofing, quick drying and plastic bonding and carries a higher per-unit price tier; ATack (B0BJ3345L6) is a matte black, 100% waterproof silicone sold in an 8-pack with broader surface sealing use but has mixed reports about drying and ease of removal. Choose Loctite if you want a premium, quick-drying adhesive for plastic and waterproof repairs; choose ATack if you need matte black sealant in bulk for general sealing and bathroom renovation jobs and can accept some variability in drying and removal
