I'm Mark and my wife is Jerri. We are brand new to the RV world and have lots to learn! We have just purchased an 2021 Imagine 2910BH. I hesitated in starting with such a long trailer, but we hope to make many road trips with some of our grandkids ranging in age from 14 to 3 months! We haven't even picked-up the RV yet, but will in a couple of days. One option the dealer is offering us is the exterior protection coating "First Place Finish". Does anyone have experience with this protectant coating? Would you recommend spending the $750? Thanks, Mark
