Autogeek has a awesome forum as well as a retail site. So does out great vendor here Adam's. They also have a forum and retail site worth checking out. honestly its a bit dangerous. it will make you spend money like here does haha. seriously tho there is a ton of great info there and it will help you maintain your paint/vehicle a lot better.
there are lots of options to try out. right now i like McKee's 37 Hydro Blue Sio2 Coating. you wash off the soap,then spray this on then just hose it off then dry. it adds a coating on your paint. i then spray with a detail spray as i use a drying towel. Dont use a shammy they are not good for your paint. i only do this in between waxes. 2 times a year ill do a paint correction, seal, glaze, wax. i apply these with my flex orbital polisher
another awesome product to check out for quick paint corrections with wax is HDSpeed. its all all in one and gets amazing results.
