Parts Desk Insights
Best Use Case: Great for sealing and bedding marine components where you need a durable silicone rubber sealant that bonds well to fiberglass, metal, and wood.
Common Issues: For best results, start with clean, dry surfaces free of grease and contaminants. If the area has weathered material, cut back to solid, sound substrate, then apply sealant and allow proper curing conditions before loading or exposing to water.
