I need to purchase some more S100 and was debating whether to buy more of it (or another carnuba) or just layer with aio. In the spring I : wash, clay, wash, polish/enhancer, aio and then s100. I usually reapply s100 every month or so. could i just layer/reapply aio and skip s100? products I like are easy on/off with no set up (haze) time and leave no residue. suggestion? maybe nano wax? or other carnuba's (blitz, etc).

 

AIO will strip and remaining S100, so you can go ahead and apply it right over top. I would top it with something though, since AIO doesn't offer a ton of protection. If you want something super easy here are a couple candidates:

1) Optimum Car Wax. Spray on, wipe off. You can do the whole car in literally 10 minutes. 2-3 months of protection and a nice look (looks similar to S100)

2) Duragloss Aquawax. This stuff is all the rage at Autopia now. It's available for under $10.00 and looks pretty amazing. Same deal, spray on/wipe off. It'll look good over AIO.

Have fun.
