Autotriz PVC & CSM Hypalon protects against damage from discolouration, drying, cracking and adhesive separation of rubberized fabric caused by extreme heat and high UV level in marine environment. It fills in the microscopic pores of CSM (Hypalon) and PVC fabric to create a smooth surface that repels salt water, dirt and oil. The sealed fabric texture also eliminates the build-up of mould and stains.
