Track question

Greetings all,
FNG here, looking to buy myself a GTR. Love the resource this forum provides so thank you all for that. Coming from a 991 GT3 and a 991 GT3 Cup.
My question at the moment is how well the magno paint holds up on the track. Track cars get a lot of tire marks and general spooge which takes a fair amount of elbow grease to remove. How does the paint handle this and what do you use to remove it?
I'll have lots of other questions as this journey moves along so please be patient with me. I imagine the next one will be about what kind of slicks folks run and what wheels they use for them.
Thanks!

The more you "rub" on matte paint, the shinier it will get. The only way to keep it pristine and original looking is to use film 😉

Get all of the matte bits covered In XPel Stealth, and the shiny black bits covered In Xpel Ultimate Plus. You want to minimise the chances of having to require a respray on the front end of the GHM as much as possible. Track detritus comes off easily with plain rubbing alcohol btw.

One last thing: a previous owner of a GHM GTR actually had the whole car protected by Xpel Ultimate Plus, and whilst that obviously took away the matte looking finish, it actually created a fantastic looking car imho.

Happy hunting!

This is the one. As said above, Magno pretty much needs full PPF. But keep in mind, matte paint with Stealth PPF looks awful if you wear polarized sunglasses.

Whether on paint or PPF, I've always used the following when doing the post-track tire-mark (and to/from track road-grime) removal:
- first use 50/50 rubbing alcohol via a soft cotton rags (I use cut-up old T-shirts)
- for remaining marks, use (Mothers pure) carnuba wax via same soft cotton rags

BTW, carnuba wax removes many types road grime, including road tar. The thing I like about carnuba wax is that I don't have to worry about it damaging the paint, in any way. I have much less trust for many of the automotive specialty products. Oh, and 50/50 rubby plus carnuba wax is often less expensive than having a hoard of specialty cleaners.

Yeah, or take pictures (it can ruin an otherwise nice shot) ...


BTW, this actually applies to any PPF. Mine is gloss/regular PPF on gloss paint.

Yes, it can. Xpel actually mentions it on their website, but it seems more prone with lighter colored cars. I've had PPF on my last two metallic black cars (current one is Obsidian) and I've been wearing polarized sunglasses forever. No adverse effects due to the PPF. In fact I can't even tell that only the front has PPF.

Don't use wax on matte paint. It'll make it shiny. Wax fills the imperfections of the paint, which is what gives the matte effect with the Magno paint, so any paste or wax must be avoided.

You cannot use any type of wax on the Xpel Stealth; only products specifically designed for the film. All I ever did was wash it with Chemical Guy's matte wash soap and then use their matte Detail Spray when necessary.

^^^This...along with many other products/chemicals that are safe for clearcoats.

Okay, very helpful responses so far. Thank you.

How long are you finding that the PPF lasts? I have seen older film bind to the paint and pull it off if let in place too long. I know the newer films are supposed to be better but none of them should stay on the car forever, right?

Film technology has come a long ways. The good ones offer a warranty, so that should clue you in on how often you should replace them, but today's PPF should be good for 7-10 years.
It can get brittle as it ages and be difficult to remove. Pulling the paint up is always a risk, but usually on panels that have been repainted or if the adhesion/bonding is poor for whatever reason. It really doesn't happen a lot when proper removal techniques are used.

Xpel guaranteed for 10 years iirc. Have it removed/replaced professionally and you’ll be fine especially if it’s applied over OEM paint. Also consider protecting the windshield with Exoshield, etc.

Simple:
Spray down with Koch Chemie Green Star APC diluted in the spray bottle 1:5, let dwell for 2-3 minutes then rinse.
If anything remains, break out the hammer, CarPro TarX, spray on, let dwell then rinse. In some cases light agitation with a microfiber towel is needed.

Many great PPF brands and models out there, if splitting hairs I prefer STEK and some Suntek product to Xpel, but all are good and I would use any.

I STRONGLY suggest you find the best installer you can afford, and don’t worry about what film they use, they all have unique characteristics in working with them, let the installer use what brand they are great at using.

XPELs popularity was/is primarily driven by its superior pattern cutting software, which to use requires film roll purchases, so that’s why you see that brand used a lot.

Also, don’t leave ANY PPF product on more than 7-10 years, it’ll be an absolute pain to get off and redo.

Just noticed this and have to say that I feel it's rather rude. You made your point about the special case of matte paint and I understand that. Personally, I never think about that case because I'd never have a matte-paint car (yes, my bad as that was the context of the question).

However, my advice still holds for non-matte paint and, given that I've used the stated techniques for decades, including on a 1983 Polar White MMZ that I daily drove for 27 years (over 0.5M mi), I have strong evidence that it's a good strategy when caring for MBZ paint.

Hey, Brother. I accidentally posted the same post twice by mistake. The ‘Delete’ was me pointing out to everyone here that my response was the one above, and that I had deleted this second, accidental post. It was in no way an indictment of your post and I was NOT asking a Moderator to have your post ‘deleted’.

Jesus!
