That's a tricky question as everyone has their own opinion.
I've tried a lot of products in a similar quest and I've come to a conclusion that anything on top of perfectly polished paint changes (takes away from) the look. Some waxes/sealants will make the paint look wetter or shinier but add a layer doing so.
I think of it like adding wax to a diamond to try to make it look better...
Regardless you'll need something to protect the paint, and I find the LSP's are very similar in appearance to the degree I doubt most could tell the difference if one side of the car was coated with wax A and the other side was coated with wax B.
To make a good recommendation I think we need to establish the variables:
1. Durability, how often are you ready to reapply the product and what do you need to protect from the most
2. Preferred quality/advantage for the ideal LSP; Gloss, Depth, Flake Pop, Glow
3. Ease of application, do you want to layer something to death or just WoW
4. Cost, price range
Honestly some people pay $1,000's for wax's that in my opinion look the same as a $60 wax (in some cases they don’t even look as good). It's very subjective.
None the less I'd recommend the following LSPs:
FK1000P, this is my current LSP and it's easy to use and can easily be applied because the tin's opening is large enough for the DA pads to fit in (4inch pads). It also has incredible durability and has really good quality’s (high gloss/shine, Good flake pop, nice glow). I've been applying this this wax in layers, one layer after my weekly washes (up to 3 layers).
Collinite 845, is another great LSP. It’s very easy to apply (can be applied via DA) looks great last longs and the price is right (Collinite is a must have IMHO). It also doesn’t stain trim.
Klasse All-in-one & Klasse Sealant Glaze, this is a two part LSP one is a paint cleaner with a sealant in it (All-in-one) the other is a pure sealant made from acrylic. This is one of my favorite looking LSP but requires a lot of time to layer (12-hour cure time between layers). I apply a minimum of 4 layers and a maximum of 8. The gloss is really incredible as is the durability.
Blackfire Wet Diamond (sealant) topped with Blackfire Midnight Sun (wax), is another combo. It doesn’t have very good durability but it looks really good. I recommend two layers of Wet Diamond 8 hours apart, and then top with two layers of Midnight Sun after letting the 2nd layer of Wet Diamond cure for at least 12 hours (layers of Midnight sun can be applied as soon as 1 hour apart).
I have pictures of my car done with each of these products below…
