Thanks,nah I just went ahead and applied it without the primer, I got the idea from a hobbyist on parts express who did the same without the primer and had no issues. The adhesive they use is pretty strong and seemed more than enough. Its real easy to apply too you just cut whatever size you need from the roll and peel n stick really. It does help to heat it up first with a blow dryer to help flatten it out and have a sharp craft knife but other than its super easy. Just be careful not to scratch it cuz when I tried to flatten my first peice I was using my palm n didn't realize I had some decent calluses going on and scratched it pretty good hahaha. I ordered a sample of metrorestyling in house cf vinyl too to compare since I need quite a bit to wrap my sub and its like 5x less expensive than 3m so we" ll see. Im also going to wrap the rest of the speaker enclosures with another 3m vinyl wrap that they have at metro,its the bubinga wood grain,its look pretty nice n should compliment the hivi woofers copper colored cone well,something different I guess,I should get that stuff in this week.
