Dear Forum Members,

Tonight I told myself - no detailing after work; go home, sit down and relax. But then I remembered...last week I received a new bottle of Mckees 37 Hi Def Paint Sealant and was itching to apply it to my Blue 2014 Audi A4. So with the wife away for the night on business, I found myself subconsciously headed for the garage.

I started with McKees37 rinseless wash; the car did not need claying as it is very well maintained. I could have used a waterless just as well, but opted for the rinseless tonight. Then came the FUN. I applied McKees Hi Def Paint Sealant very lightly and evenly by hand using a foam applicator. My applicator was a little thicker than the one Nick shows on the site so it absorbed some product but no where near as much as other sealants - this stuff is THICK. In terms of smell, it has a fruity smell to it that I would describe as a cross between strawberry and watermelon (?) with a very faint hint of chemical smell to it. Consistency and smell alone made it a pleasure to work with.

As far as removal goes, the directions on the bottle indicate a min. 15-20 minute curing time. I let it sit on the car for one hour and then decided to remove it with a new MF towel. Wait, did I remove it I wondered. I was only in the garage for 5 minutes. Yes that is how easy it is to remove! I was able to remove it from the entire car in 5 minutes flat - and I was not rushing. Still in doubt? Fold a MF towel in 4 and place it on the car with your hand on the towel....now sneeze!!! Yes it is that easy to remove and McKees says it removes even easier if you leave it on longer. I can't imagine it being easier.

After removal, the paint felt as if it had a candy shell on it. The end result is a level of slickness you have to experience to believe. I've used many other paint sealants. Some are very easy to remove and provide great levels of gloss, but this one was by far the easiest to remove and the level of gloss that is on-par with good carnauba waxes. It does not have that typical sterile look often associated with sealants.

I can't speak to durability. My car is never a good candidate for a durability tests anyway because within a month I'll be back out there doing this again :-). Next time I may top it off with McKees Trademark Poli-Coat Wax after waiting 24 hours for the sealant to cure. However, I am very interested in it's durability as that is a very important characteristic of a sealant IMHO. As such, I will be applying it to a friend's car within a week or two. This is a car that gets washed once a year (no kidding) and never garaged making it the PERFECT candidate for a durability test. The last time the test subject was washed was Christmas week 2016 at my house. Since I work with this friend I will get to monitor the durability over time as I see the car almost every day.

If this holds up the 6+ months that McKee's indicates, they have a real winner with this product. I will report back over time on that. Sorry the pics may not be the best - lighting in the garage isn't the best unless I break out all my lights - which wasn't happening at 10 PM (grin).

Hope everyone is well.

Great review! The new McKee's sealant is very nice. I let it sit for about 15 hours on my car the first time I used it and it was still very easy to remove. You've got me interested in using the product again but I don't have a test subject.

I wish I had that much open space in the garage to be able to do that.

You and I both! I'm moving into an apartment next month so my garage is going to get even smaller.
 
I took some pics of my car which I applied paint sealant to but rarely wash the car and it still beads up nicely. ill see if I can get them posted up here later today. I wish I can remember when I ordered the hi def so I have a time frame of when I applied it

Whether you bought it on AGO or from McKees...check your order history

I have the sealant on my dad's rav4. I've caught him washing his car with a mop before so... let's see how durable this is especially in Canadian winter.
 
Your post made me laugh - caught him with a mop! Classic.

Post back later in the winter with some observations

Nice review.....this is now on my Christmas wish list.....where in NJ are you...I'm near Atlantic City
 
That stuff is awesome. If you like slick paint, wait until it's fully cured.

I used it on my mother-in-law's Lincoln MKT. It's gone through a brushless car wash I trust once, and been washed with meg's gold class once in 3 months since I applied it. Still beads like mad, and is slicker than snot.

How long do you let it cure before wiping off?
 
I would always suggest if you have time for as long as possible but at least 15 to 20 minutes. I like to wait overnight if possible, that's when I find it looks the best and has the slickest finish.
 
so can I clay my vehicle, than use poor boy's black hole glaze & then top off with McKee's 37 hi-def sealant ? or even if I decide to use 3D- speed or McKee's 360 first before the hi-def sealant ? thanks

You're making more work for yourself than you need to, and I don't know that I would mix product lines like that as I've had some poor results in the past. 360 has fillers (I believe anyway), and decent durability. Not as good as Hi-Def, but my experience with 360 is the durability is good enough that it's not worth another coat of sealant. With regular washes and the occasional top off with some sort of spray wax (Megs ultimate and McKees fast wax have worked well for me) you'll get through most of winter.
 
Cool stuff. Good to know, for the next time I need sealant. Will be a while, though, that's for sure.

Side note...now you have me wanting to install fans in the garage! haha.
 
Normally the wax is applied after the sealant. Doubt you will get the results you want / looking for, sealant needs clean paint to bond / cure to the surface, then apply wax if you want.

Should be clear HD Speed has wax and 360 has sealant built in.
 
Yes, and an AIO has polish, which will remove any fillers from a glaze, which is why they're called "All In One".

Sometimes the lines blur on where a product falls, but do a search here and look at HD Speed and 360. They're favorites among the AIOs for a number of reasons. Easy to use, good correction, and decent protection durability.

let me throw this out there. and by the way, I'm trying to avoid removing to much clear coat. my truck is black & I can't keep chasing down every swirl mark or light scratch(and you know there's many). how about claying then using my rupes white pad with ultra fine compound & then using McKee's Hi-Def sealant ? I don't need to remove every swirl, but I'll probably remove quite a few. and then using the hi-def sealant should mask a few. what's your opinion on this plan of attack ? the dodge ram paint is soft & not hard to remove swirl marks. I just think I'm doing to much correcting & worried about the clear coat getting on the thin side. I'd probably use the white pad for the sealant to. I read somewhere that the rupes white pad & ultra fine compound is pretty safe to use. thanks,

I wouldn't expect Hi Def or any sealant to hide swirl marks. But your plan is sound - remove the defects as best you can then top her off with protection. Then the key is to exercise proper wash techniques and maximize the time needed before the next correction is needed. I know black is 'easier said then done' kind of color but proper washing (and drying) can dramitcally reduce how often you need to do correction. If you don't already, get in the habit of using a spray wax as a drying aid/lubricant as you dry. Not only will this boost LSP life but will make a notable difference in drying ease.
