I want to elaborate a little on what is considered normal 'wear and tear'. Often times other PPF installation companies pitch PPF as an impermeable force field for your paint. XPEL paint protection film is impact-resistant from a .75'' diameter object at 140 miles per hour! For only being 8mils thick and almost completely transparent that is very impressive! The engineering that has gone into XPEL Ultimate Plus is the result of over 15 years of experience manufacturing film! Again self-healing prevents swirls and chemical burns but once the actual integrity of the film is compromised the piece will need to be replaced. Some companies pitch self-healing as if gouges in the film will heal. This is not the case with any manufactures PPF!
