stretch vinyl

Hi everyone, hope you're all enjoying Christmas holidays :D

I recently vinyl dyed majority of plastics in my car (Duplicolor Black Spray Can) even after a couple coats and weeks of 'treating', my car keys can scratch it back to gray, this is not good enough for me...

So I'm going to vinyl wrap everything now, for anyone in the business or with knowledge, could you help me out?

I've found vinyl at spotlight (arts n craft place) but I think it's only 1 way stretch. Where can I get this mythic 4 or 6 way stretch vinyl the internet talks of?

I have all the tools, heat gun, sharpie, roller..

I still need to know what type of glue and where to get the right vinyl.

I'm using the spotlight vinyl for my door cards because it doesnt need much stretching with the simple mods I'm doing.

Thanks guys.
