I would recommend maybe starting here:
Klasse All-In-One, Klasse High Gloss Sealant Glaze, Pinnacle Souveran, Pinnacle Crystal Mist Spray Wax come together to create a forum favorite kit.
Are the stripes on those vinyl? If so, did you go over them with anything? Just curious, my dad's mustang has stripes like that but they're a bit "weathered".
:( Correct, if that were that case most likely it would have to be repainted. Do you by any chance live in an apartment complex, or any kinda of living space where balconies overhang parking spaces?
I was using 3m blue masking tape. I ended up just giving up and throwing a coat of wax on it, Room mate didn't notice until I pointed it out, and didnt really care.
