Arm-R-Seal Oil-Based Topcoats are made with the highest-quality urethane resin, making them extremely durable and long-lasting. Formulated to be wiped on with a cloth or applied with a foam brush, this ambering finish penetrates to provide deep-down protection for that "natural" look. Arm-R-Seal is a PFAS-free topcoat, and as General Finishes strives for a cleaner and healthier environment, all future product development will be free of “Forever Chemicals."
