Hi, we've been applying Nano-Clear in the Wellington region to painted surfaces. Nano-Clear is a permanent clear coat protection system that will rejuvenate and protect almost any surface. It restores colour and gloss on faded and highly oxidised surfaces, fills in and restores scratched surfaces, it repairs UV damage, and then protects the treated surface for at least ten years. Nano-Clear will coat and protect stainless steel, aluminium, copper and brass surfaces. Check out our website and see
