Really do hate this stuff. Great when it works but then……. Anyhow my mirrors looked like crap with the mold underneath, as well as the front of the hood and across the top of the front cap. What I’ve read is the lifetime guarantee is of little value because of “outs” about cleaning and maintenance. So, with a YouTube video or two I ordered a 100 pack of plastic razor blades and a can of pro goof off.(there are different levels of goof off). Quick story: at my Lowe’s there were 2 workers talking as I came up. I asked where can I find goof off, and the younger guy looked quite perplexed. He thought I was talking about him, the other older worker noticed this also and explained what I was talking about. Anyway they took me to the right shelf.
so if you get the inclination figure about 2 hours per mirror. Lots of soapy water and go very SLOW. Just use the very corner of the plastic blade and don’t go more than an 1/16” at a time. Cut and soapy water each pass. Use a very shallow angle with the blades and change often. From experience, don’t try and pull on the plastic film, IT WILL LIFT OFF A LAYER OF PAINT. That is going to require another project, but I have color matched paint. Getting the glue free will require lots of the pro goofoff. Soft rag and a lot of rubbing. Don’t know yet if I want to tackle the front of the hood.
