I know, very nice gesture by Mazda to send customers free touch up paint.
Well I called a local guy here in Michigan named Greg with a company called Paintshield and he said he installs all kinds of film and whatever is best for your application. He uses Avery, Venture Guard, 3M, and X-pel. I thought I'd share the information that he gave me about putting a clear shield on a white car. Most of the films are very similar in price so he didnt speak much about that. I'm going in tomorrow to see the different products, he was out of the office today installing shields on 3 Ford GT's and wont be in the office until tomorrow.
Avery/Denison is the clearest of the films and they put a sealant over the top of it so it wont discolor as fast and is harder than a Venture Guard so for a white car this is the best option.
3M is the thickest material and has an orange peel texture, it changes the color the quickest even without sunlight, its the adhesive reacting with the film that causes it to change color. He did a show car that was never in the sun and it still changed yellow so its not recommended for lighter color vehicles.
Venture Guard is probably the worst for a white car because it doesnt have a clear coat so it will lose its gloss coat and yellow quicker than others. It's one of the thinest films so its the least durable which also makes it the cheapest. It looks really nice on darker cars because you wont notice the dulling or yellowing as much as on a white car. He also said the last five rolls he got had imperfections in the film and he wasn't too fond of the material.
X-Pel is probably the most expensive, they use the X-Pel layouts more than they use the film because of the expensive material. Still a good film but he didnt mention much about it.
3M warranties their film for 5yrs from yellowing while Venture Guard has a lifetime warranty on bubbling, cracking, or yellowing. I will find out tomorrow about the warranties on the other two companies. All companies only warranty the film not the labor to put it on which is 80% of the cost.
Hopefully that helps in anyones decision making. I've talked to three different companies about this now and think I finally made a decision to go with Avery. Damn only took me a month to do the research.
