Good morning all! I am also the proud new owner of a 2019 CB300R! I've had it about a month, went with the black and silver, and it's my first bike too. Been having a lot of fun and staying safe out there. I also read that any kind of wax shouldn't be used on the matte plastic parts. I see that ArmorAll makes an exterior matte finish protectant, that looks promising. I'm gonna give that a try, hopefully it won't stain!
