HD Speed. Good balance between correction and protection. Real easy to work with as well. Like, real easy. You can use it as an LPS with no need for further protection as that is what an AIO is suppose to provide.
if longer protection is key, might it be better to use the proper polish then apply a WOWA sealant since they are so easy? Something like the OPT Optiseal or BF Crystal Seal?
I used Essence and Reload with a MF pad on mine for winter since it got late in the year and was lucky to get a good day of weather in Dec here. I just wanted to protect till spring when I will do a final polish and probably coat with WG uber paint coating. It really did come out pretty good for an AIO on a car that is almost 7 years old.
