In reality, there's no LSPs that can significantly "transform" any white paintwork.
If you want the highest level of looks on any white finishes, look into the quality of your paintjob first.
Then, you'll have to extensively prep the surface first....wet-sanding, compounding etc. This'll give you the most significant aesthetic improvement before going into the cosmetics (waxes, sealants etc) that'll only give a marginal increase in glossiness on white finishes.
Note: Certain LSPs might bead water very impressively and last a long time, BUT, makes it very difficult to remove the usual stains. Many of my experienced customers who wash their white cars 3-4 times weekly don't even want any LSPs!!!....the paintwork is extensively sanded and prepped to achieve that wet-look, and they just use spray-type detailers. No waxes, no sealants etc. Such cars never had any problems with stubborn stains and watermark problems, and look great consistently throughout the week.
