hey,

i was thinking of wrapping my car in a vinyl matte color and i was wondering if it will stick to primer.

Does it have to have special coat of fusion paint?

Thanks in Advance.

 

no i doesnt need fusion paint, but it tends to adhear better to gloss surfaces. i really comes down to the brand of vinyl you use some stick better than others

 

yup. I would clear, if not it def could not stick to unfinished paint.

 

Here's an idea...paint your fucking car instead of buying vinyl...faggot.

 

BTW it'll prob cost the same amount to paint your car something normal colored. unless your going to try it yourself which will turn in to a big wasteball of money.

 

Throw a coat of paint or clear on it over the primer, or whatevers cheap. Then you'll have a fallback plan when the vinyl starts to get ratty. Vinyl sticks better to gloss though, the surface area is much greater so the adhesive has a lot more to stick to.

Anyway, I'd shoot it with a color coat over the primer, even if you don't clear over it. When you remove the vinyl later you can color sand the paint and clear over it then if you want.

 

thanks for all the advice, i definitly thought the opposite regarding the vinyl. I thought it would stick the same way that primer sticks to sanded surfaces.

to the douche with the miata if i wanted to paint my car i wouldnt ask driven for advice i think that topic has been covered thanks..

 

How much surface area a film is able to stick to (whether it's a paint film or something like a vinyl film) directly affects the shear strength and peel strength of the bond.

I guess you could think about a primed or sanded surface as a bunch of peaks and valleys. The peaks and valleys are different sizes, with matte paint or primer being much smaller than sanding scratches.

Paint sticks to sanded or primed surfaces because of the greater surface area.
But, paint is a liquid, so it can conform to whatever it comes in contact with, both peaks and valleys. The adhesive on vinyl isn't really liquid, and can't conform the same way, so will instead tend to stay on top of the peaks and not go into the valleys, so it actually uses much less surface area. So in this case with vinyl, because it can't actually use the greater surface area from sanding or a matte finish, you'd want to have the greatest surface area it can use, which is a gloss surface. This is why vinyl is a lot harder to get off after a few good hot days in the sun; the adhesive will get warmer (and more liquid) and will flow more into more of the surface features of whatever it is stuck to, increasing the surface area. It still won't ever get liquid enough to fill in a sanded or primed surface though, so a gloss surface is still better.

 

good shit fab, thanks for the info

 

For once, someone on this site explains something about vinyl and its adhesion properties correctly without me interjecting. Rep + for that explaination.
