I tend to wrap most of my cars in some way or another, my last car, saab 9-3 convertible had a horrid fake wood dash as standard, it lasted 4 days before I couldn't stand it any longer lol carbon vinyl to the rescue. Dash panel, binnacle and gear surround done and it looked more like a sporty car inside. I couldn't stop there though and did the whole car in a metal flake black vinyl with two Matt black stripes on the sides. It looked great, even the guy who smashed into me at a junction thought so lol shame he wrote it off
I think done slowly and with good quality vinyl a DIY wrapped car can be done to look 95% as good as a pro job.
you've had some great advice on here, you've made a few mistakes and had some problems but then if it was an easy thing to do there wouldn't be a need for professionals. As for the colour, it's your car and if you want that colour then good for you.
my top tips for others trying this would be :-
do it in a none dusty environment, if you do it in your garage at home make sure it's not windy as drafts can whip up dust and ruin the finish.
clean the car extra well, use paint prep wipes ( I like wipes over liquid and a cloth as wipes don't break up or leave bits like cloth can do ) and don't miss the corners.
use decent vinyl, cheap stuff is very tempting but a false economy as it rips burns tears and causes more errors so you end up using far more and could have done a better job with less waste for the same price
take your time, it can be tempting to want to rush in and do the big, easy to do panels so it looks like your really cracking on but you'll learn far more doing some smaller more testing panels, learning how to best work the material and what techniques work for you.
if possible get a nice warm environment. Some people like room temp but I find having the room warm just gives that tiny bit more pliability so you don't need to reach for the heat gun or hair drier quite as often.
Remember to to let it dry or cure after. It's no good taking it out in a monsoon five mins after you've finished as chances are you'll just ruin all your hard work. Also try to avoid extreme sunshine for a couple of days, I have no Idea why but some cheaper vinyls don't react well, odd but true. Could be uv rays or something I have no idea.
these are just my thoughts, I'm not a pro but I do have quite a bit of interior and exterior wrapping experience.
Good luck to you all
