Paint Stripper may soften or even dissolve some plastics. Please check beforehand by testing a small area and seeing if plastic if affected. Do not allow coating of Silicone Remover to dry out during use if conditions are hot or windy. This can be achieved by encasing or wrapping the surface in clingfilm or enclosing individual propeller blades on plastic bags fixed in place with elastic bands or cable ties. This product can be used elsewhere as a general-purpose silicone remover, to remove silicone residues <0.5 mm thickness. PropOne Paint Stripper can also be used to soften and aid removal of other coatings used in the marine sector such as antifouling, 2-pack epoxy, decorative alkyds, enamels and clear coat varnishes.
