Oh the struggle with black paint! To start out, I bought my Attitude Black Metallic 2015 Toyota 4Runner Trail Premium new in August 2015, and black was not my preferred color due to maintenance to keep it looking good (this is my second black vehicle that I have owned), but I got a killer end of year model deal for what was on the lot, and the trim was exactly what I was looking for. The first winter it went through automated car washes (usually not touch free) many times, and come Spring the paint was a swirly mess. After much research here on the forums and some advice from you guys, I purchased a setup (Polisher is a PC DA 7424XP) and finally got around to detailing the truck in December of 2016. After a good wash, and Nanoskin Autoscrub, I buffed with Menzerna SF polish, to find that I needed something more aggressive. After buffing the entire truck with XMT #3, then following up the entire truck with the Menzerna SF polish, the swirls were gone and the truck was looking good. I sealed with Menzerna PowerLock, and was happy with the results. Fast forward almost 6 months, and after ONLY hand washes done by me, the truck has quite a few swirls again, nowhere near as bad as previously, but more than I was hoping to see. I use a pressure washer with an MTM Foam cannon, using Chemical Guys Honey Dew, with a sheeps wool wash pad, that I rinse in a bucket with a grit gaurd, then dry with Cobra guzzler waffle weave towels. Is there something that I should be doing differently to avoid the swirls, or is there a better seal that will protect against the swirls better? Should I expect to have to buff swirls out every 6 months or less?
