Overall, good. My main gripe is that the cut outs aren't 100% compatible with my 2003 mustang. The cut out layouts are accurate, but it was meant for a piece of the car that won't work. The lower door wrap is the lower car door, which has carpet on it. So, it would require me to extract the door panel to remove the carpet panel to apply the vinyl in its place (which is more work than it's worth). Most people at this point would probably give up, trash the product, and leave a negative review. However, I'm an artist, so I was able to repurpose some of the cutouts and create something beautiful (yet quite different, than what was initially presented).
Despite the shortcomings, it looks great, and enhances the interior of the car. I will say that the application videos on youtube are a bit dated. The videos go a bit too deep. The material is far more forgiving than I realized (which is a good thing). I made many mistakes, and was able to remove and reapply to perfect the strips to my liking. You have to be patient. The adhesive promotor is necessary, as long as you have a blow dryer, or heat gun to seal the deal. It will stick and mold to hold with heat. Also, I have the 3M pen applicators to go back over edges, to get it even better for a tighter bond.
I also plan to apply spray gloss protection on my vinyl to protect the integrity and colors (from sun light and oils from the skin). Take your time, and it will look amazing. Smooth out the bubbles. (Use a blade to make small cuts if you have to, - if done properly, the cuts are undetectable). Certain cuts may not be perfect, and you may have to be creative with your designs. It may be worth having a conversation to verify the compatibility of your car model. Overall, I like it, but it could be better.
