I have the matte Shaker stripes on mine. I use Meguiar’s Gold Class for maintenance washes for the whole car and have tested multiple products on the stripes for protection.
303 protectant, works fine but only lasts maybe a month.
Meguiar’s Ultimate Liquid Wax, works great, it’s a synthetic sealer and adds a slight sheen.
Car Guys Plastic Restorer, awesome product for anything rubber, vinyl, or plastic. Has hydrophobic properties, UV protection, restores your faded trim beautifully and does not add any sheen or shine. Only downside it’s about $16 for 8 oz. however a little goes a long way. Applies similar to a wax, buff on buff off, mine has lasted for 5 months so far.
