What is the OBJECTIVE MEASURE of a good LSP???

What I look for in my LSP, in order from least to most important:
· Gloss/Reflectivity
· Ability to repel dirt\dust and prevent it from adhering
· Winter durability against road grime spray (salt/oil/grease/sand/aggregate)
· Water beading/sheeting ability
· Ease of application
· Longevity​

LSP goals:
· I want my car to shine/glimmer in the light like a freshly polished gem.
· I want a LSP that helps me with the cleaning process to reduce marring and swirls. A durable LSP that doesn't attract dust and pollen like most wax's do.
· I want a LSP that can last at least 1 month in the winter and still provide the things I look for in a LSP (high gloss, repel dirt/grime, bead water). So far, none of the LSP I've tried held up. Water beading is basically nonexistent on the lower panels and rear of my Jeep within 2 weeks of application.
· I want great water beading and sheeting to remain after multiple washes (at least 2 months in the summer and at least 1 month in the winter). So far, most of the LSP I've tried do hold up in the summer but not the winter.
· I like a LSP that’s easy to apply and remove, I don't want to be fighting to knock it off (happened to me with Klasse Sealant Glaze at first because I put it on too thick).​

LSP issues:
· Out of the LSP’s I’ve tried only one (maybe two) has significantly enhanced the gloss of my paint (fully polished and prepped there’s very little improvement LSP offer, IMHO). I find wax's dull the look and enhance the depth (cut the glare).
· Most (if not all) of the LSP’s I’ve tried do repel dust and dirt at first but quickly fall off after a few washes.
· None of the LSP’s have been durable enough for winter and by this I mean the LSP may still be on the car but the properties (gloss, repellence, beading/sheeting) are vastly diminished or even non-existent (noticeable on the rear and lower panels only).
· The water beading and sheeting has been a mixed bag for me, some do this every well, some do it very well but only for a short while.
· Most of my LSP are easy to apply and remove with one or two exceptions of course.​

List of LSP I’ve tried with my subjective opinion on the criteria I look for in a LSP:
· Blackfire Midnight Sun – did not improve gloss, attracted dust/dirt, never tried in the winter, great water beading but didn’t last long, wasn’t easy to apply and remove, and didn’t last long overall.
· Blackfire Wet-Ice – improved gloss, repelled dust/dirt, never tried in the winter, great water beading, was extremely easy to apply and remove, still going 2 months after application.
· Chemical Guys 50/50 Connoisseur Paste Wax – did not improve gloss, attracted dust/dirt, doesn’t last in the winter, wasn’t easy to apply and remove, and doesn’t last long.
· Chemical Guys Butter Wax – improved gloss slightly, attracted dust/dirt, never used in winter, very easy to apply and remove, doesn’t last long.
· Collinite Liquid Insulator Wax 845 – Gloss remained the same, dust and dirt is not attracted or repelled, lasted very well in the winter on upper panels, easy to apply and remove, lasts a long time overall.
· Klasse All-In-One – Gloss remained the same, dust and dirt is not attracted or repelled, lasts very well in the winter on upper panels, easy to apply and remove, doesn’t last as long when not topped with Klasse Sealant Glaze.
· Klasse Sealant Glaze – significantly improved gloss when layered 6 to 8 times, repels dust and dirt for a short while, lasts a while during the winter on upper panels, difficult to apply and remove, lasts a long time overall.
· Mothers FX SynWax Paste – improved gloss slightly, dust and dirt is not attracted or repelled, doesn’t last in winter, easy to apply and remove, doesn’t last long overall.​

Summery:
I still haven’t found the perfect LSP or the perfect combination for my needs, but I do have LSP protection year round with the products I own. I wouldn’t mind having two different LSP’s to suit my winter and summer needs. Right now, I’m seriously leaning towards a high gloss coating for my Jeep SRT8 as I will be parked outside the majority of the next two years (moving to a house without a garage). IMHO it’s been hard to find a high gloss LSP because most LSP’s offer depth and flake pop when I really want something that looks more like liquid glass poured on my car. Note: I dont think a coating will be the most cost effictive if I need to have a pro install it.​
 
MiVor- Eh, I feel dumb as I've seen your posts on the Auto Armor! Completely slipped my mind. I'd still be a fanatic about cleaning those out-of-the-way areas during the winter though.

Beading/sheeting/water behavior *over time* does IMO indidcate something. I don't like to let my LSPs go for so long that such behavior changes.

I'd leave out the "cost-effectiveness" as to me that's purely subjective; everybody has a different threshold of significance when it comes to spending money.

Understood.

Then maybe we should all spend some real $ and have the rides clear-bra'd and not be concerned about LSP's? ;)
 
With some of the newer self-healing PPFs I guess that's not as silly as I might've once thought!

I don't think they are silly at all if we're talking about something like XPEL Ulimate. I can definitely see an argument for getting at least the nose filmed and perhaps the entire hood, side mirrors and front fenders but it all depends on the car and what issues you expect to encounter. PPFs have improved immensely relative to what was available ten or twelve years ago.

On the issue of LSP longevity I'm perfectly happy with the ability to reliably survive for six months on a daily driver through a a Northeast or North Central North American winter, extending that to two or three years doesn't add that much value for me.

Looks, of course, matter but on daily drivers the only time looks becomes the dominant criteria here in the Northeast for me is that sweet spot after the end of pollen and peak insect season and before winter prep - maybe July through October.
 
LostHighway- Yeah, the XPEL Ultimate is what I was thinking of. I'd had previous PPFs and seen a lot of them, but I hated the look so much I'd generally rather have stonechips. Heh heh, had a few chips happen right *through* the PPF almost immediately anyhow and wasn't a big fan of dealing with the edges..so I was generally pretty negative about 'em in the past.
