Seal N Shine is the GOAT but it is an older product. Modern products have no significant results advantage over Seal N Shine but they do have an advantage in user experience. Not that Seal N Shine is difficult. It's not, unless you use too much, then it can be streaky and grabby when buffing. Seal N Shine is good for any color. It's applied like any spray sealant. Spray a couple of sprays on a panel, level it with a microfiber, then buff it with another microfiber, move onto the next panel. The sealant I would recommend these days is Collinite Beadcoat. Not something you will find in any stores but it can be ordered from Amazon or other online locations. But personally, I still like waxes. Soft99 makes a high gloss wax specifically for light colored vehicles called Kiwami. https://www.amazon.com/SOFT99-EXTREME-GLOSS-WHITE-Soft/dp/B0F9LNL1ZB/ It's old school wax on/wax off, the same way our fathers and grandfathers did it. "Kiwami" is Japanese for "Extreme" (it's a wax made in Japan). When it comes to gloss and hydrophobics, it's legit. A spray sealant is going to be easier and faster to apply. Kiwami is going to look the best. One tin of Kiwami will probably last you the life of the vehicle.
