You know.... whether or not a "sealant" or a "coating" is the best thing for your brother more or less depends on how he plans to keep up with the paint on his new ride.
If he's the type that enjoys spending time with his vehicles on a regular basis, keeps them washed, likes gently caressing the paint with QUALITY microfiber towels, and upon occasion re-applying said "sealant(s)" and/or 'boosting' a "coating" then there are as many questions as there are answers.
Coatings are all the rage, and certainly provide longer lasting protection. Yet all I've seen (so far) have at least some sort of maintenance product that needs to be applied. There is one though that does not (either have, or advertise) and that is Duragloss Enviroshield. Not saying it wouldn't benefit from the use of a similar product, (and I've used Pinnacle Black Label Diamond Coating Booster) on DG coated vehicles.
Directly from the product page: "
Think of Black Label Diamond Coating Booster as a spray wax for coated vehicles".
OTOH, using a sealant you'll have to wash, decontaminate, and reapply at least every 6 months in the Florida weather. (
Not like a coating, (PBL or otherwise) isn't recommended to be "boosted" every 6 months either.) :laughing:
FWIW, if your brother's vehicle EVER manages to be around any sprinkler water I'd suggest he forego the coating as it's just an added expense. I've had experience with the
UNGODLY St. Augustine sprinkler water on a freshly coated vehicle, as well as on one with multiple layers of WGDG Liquid Seal (WOWA version) and it trashed them both!
The one with the WOWA sealant ended up needing a multi-step paint correction (
AGAIN) to remove the water spots and etching.
The one with the coating
buffed out easier, much easier in fact, but buffing a coating means it's GONE. (IE: Needed to be totally reapplied from scratch.) It was actually corrected with a black CCS pad and Menzerna finishing wax (only a 2 on the cut scale) but that was still more than almost all coatings short of OC-Pro and maybe Modesta can endure.
