It's been a couple years since I did my canopy but my initial holes were all number 40 and then any holes after that you want to have a backer made of wood or UHM , if you need to use one of your regular bits you can dul them by drilling into your concrete floor for 10-15 seconds and the only thing you can use it for now is plexi
Give your glass all the room you can to expand & contract ,,, 2 Of the 4 RVs in my county have cracked canopies rite now , fingers crossed every time I close mine these cold mornings !
