Just take the time to use Hyper Polish to get the correct surface. You're risking potential micro marring and unseen factors preventing a clean installation. Why risk the cost of the product off of a few hours of work?
Had OC go through 1 tiny snow storm in NC (its NC... smelt everywhere). 2 clients complained of slight water hugging on the lower side panels. I suggested they use Opt's QID/Spray Wax, no issues after 2 weeks! So yes it does fine from what my clients tell me.
What's everyone's go to way to clean pads besides hand/washer techniques? Its the worst maintenance that I have to do. MF pad wise I've found using a grit guard as a scraper dislodges a heck of a lot of the polish residue.
Always try DIY a pad washer.
