Did the other one and bunged it on the car this PM. My only worry is it unsticking. The B pillar vinyls have needed gluing back on in places, will need removing, cleaning and redoing. Which I am deeply not wanting to do!
You don't need to glue it at all. Where did you buy the vinyl from? If its a good quality brand then it should not come off but if its an unbranded from ebay then chances are the adhesive is not sufficient . Another reason why it might not stick is that the B pillar or any area of the car you want to stick vinyl was not cleaned properly.
Ideally you clean the area and make sure its dry then you use IPA aka isopropyl which is an alcohol just to make sure you remove any dirt that you cannot see.
If you do not want any vinyl to peel you need to seal the edge once you applied the vinyl. The way you do this is using a heat gun (or a hair dryer) on the edge moving side to side and press the vinyl down making sure its stuck well therefore sealing the glue and this stops the lifting.
If you need black carbon vinyl I have some by a company called Ritrama. I got some sitting not being used,about 1 square metre. You can take of for £10 + post if you want.I had used it on my 147 B pillar for a year with 14k miles as well as the rest of the whole car and not peeled off. I have just recently remove it as I need to sell the car.
It was decent quality stuff, it was fine until last winters frosts, then it started to lift on the inside edge where the door meets the door rubber. I reckon it got stuck to the rubber with ice and pulled away a bit. As it was so cold and wet, the effect slowly travelled down the door. A line of hot glue cured it, but it does need replacing somewhen as it upsets me.
