I just watched the Legendary Auto Interiors video on how to install a vinyl top.
Oh boy, they did nearly everything wrong and the final install gets a grade of C+ at best in my book. The way they did it is messed up and ill informed. Whatever you do, DO NOT do it the way they showed.
I watched 3 other videos on how to install and they made all the same mistakes.
I did thousands of vinyl tops and the results these guys are showing suck. If I ever did one that looked like that in the end, I would have ripped it off the car and started over.
