I planned on vinyl wrapping my window trim gloss black and have some left over vinyl to wrap the valance I was just wondering if I should stick with the gloss black for the valance or if i should get some matte black vinyl instead

 

Personal preference really. Some like the matte while others like the glossy look (similar to carbon fiber). What finish are your wheels? That could help with the decision.

 

stock 17's atm but i plan on upgrading in the spring, i may plastidip them black for the winter

 

If your G is black than matte for sure, but gloss would go fine for the other body colors. It's best if you can drop your mufflers down a few inches so you can wrap up into the exhaust cutouts without interference from the muffler tips.
