darn it, i’m sorry! i thought i put it in the description but i forgot. these are what we used for the skins… Aluminum Blind Rivets with Aluminum Mandrel, Domed Head, 3/16" Diameter, for 0.126"- 0.25" Material Thickness www.mcmaster.com/97447A050 item number 97447a050. we are not affiliated with McMaster-Carr, but their shipping is quick so that’s been nice to have every time we ran out lol. i believe the original rivets were 1/8” but some of the holes in our were loose… probably from being drilled out and replaced before, so we decided it was better for us to go up in size for all of them… but that’s just a personal preference! also, to estimate, i believe we went through about 2500 of them in case that information is helpful at all when it comes to estimating how many you may need to order:) best of luck with your project!!!
