My regime is determined by the seasons. I do a full wash, clay, deep clean (paint cleaner with no abrasives), and sealant...in November and April. That means I need a sealant that lasts 6 months. My choice is DG 105. Easily gives me 6 months including taking it through local touchless car washes in winter if I get lazy. It won't hurt 105.
Wax is optional. I'm not a wax fan so I only apply before a car show. Wax creates a dust magnet and as far as I'm concerned that defeats the whole purpose. It's for looks only in my opinion and adds nothing a sealant can do in terms of protection.
Notice I never mentioned polishing. Taking off clear coat is not something I will do at this point. My paint is optically clear with a couple of scratches that aren't noticeable unless you are a contortionist. I've perfected my washing and drying technique. Took years actually. I also no longer " spot clean" between washes. Forget that. I wash once a week or bi monthly and I don't touch the paint in between washes. Trying to keep your paint dust and dirt free on a daily basis is futile and I've learned to just live between washes without the urge to spot clean.
It's all about washing, drying , and adding layers of protection. My DA polisher only comes out to apply a chemical paint cleaner 2x s year just before the sealant. The new DP product looks like a winner. I don't use chemical strippers or soaps to remove sealants. I polish them out with a non abrasive paint cleaner. After six months the sealant isn't going to put up much of a fight, and the paint cleaner restores optically clear paint.
