Suggestions for coating a PPF car

[bryanviper]

Hello All,

Just wanted to get your opinion, My mechanic would like my to coat his black Lamborghini Huracan (I think) which is fully PPF'd. I'm looking to use GTechniq EXO v5 and CSL Kit 50ml for the coating, hopefully its enough for the full car. This 2 part coating should be fine on PPF correct? I dont need to use one of the special PPF made coatings?

This is what I'm planning to do, please let me know if you see any issues.

Wash - CarPro Reset
Decom - Either CarPro Trix OR GTechniq W6 Iron and General Fallout Remover?
IPA - Gtechniq PW Panel Wipe
Coating - GTechniq EXO v5 and CSL Kit
Topper - Gtechniq C2V3 or C2V4 if its out by then

The PPF he got installed on the car a year or two ago has Ceramic build into it but its worn down according to him so he wants it coated. & since its PPF he said no Polish as im pretty sure its self healing too so its likely in good condition?

Any suggestions or tweaks to what I'm thinking please let me know, I have experience and prefer Gtechniq products or even carpro/gyeon

Thanks

To me it sounds like you need a new mechanic.

If the PPF coating is failing, it's the person that sold you the product's problem.

If that didn't get me anywhere, I'd use a decent spray ceramic after every wash and call it a day.

Why would I need another mechanic? That has nothing to do with the PPF he was sold.
That being said does that ceramic properties of the PFF wear off overtime? Like a coating on paint?
Could it be that it just needs a good Decom wash?

he wants a proper ceramic coating not a spray ceramic that he needs to put on regularly.

Thanks

My bad I read that as your mechanic wanted you to get it done.

The thought still counts. The day I protect a big piece of tape on the surface of my car with some more expensive junk, please take me away. Any modern spray wax will keep it beading for ages. From my understanding most traditional coatings don't adhere well to scotch tape... Err ppf.

1. 50ml is more than enough for a car; generally 30ml is plenty aside from larger SUV’s. No real need for PPF-specific coating for the most part although usually they are easier to use.

2. Plan seems sound although Gtechniq Panel Wipe is pretty aggressive as far as panel wipes go, never really liked it much. CarPro Eraser is pretty lubriliscious as smells divine as well.

As for “Is it necessary?” Perhaps a good decon/wash would be enough to put a smile on his face.

I’ve got two cars fully PPF’d; one with STEK Dynoshield w infused topcoat (2019, 25k miles ago) & one with XPEL Ultimate (no infused topcoat (2021, 30k miles ago). Both were ceramic coated at PPF install time.

As PPF & ceramic serve different purposes, the ceramic serves the same benefits as it does on bare paint; long-term good looks, enhanced chemical/environmental protection & ease of maintenance. The STEK w infused topcoat does degrade over time and (in my opinion anyway) doesn’t provide the same long term protection as a true ceramic coating, hence I had a PPF-specific coating applied. Any coating on PPF will not last as long as it will on paint in my experience; I recoated the STEK car after 3 years with a non-PPF-specific ceramic.

The non-infused XPEL car was coated after PPF with a non-PPF specific ceramic & it’s still doing extremely well given the daily driver, 4-season usage of the vehicle.

Was all that necessary? You’ll have just as many opinions on that as there are ways to care for a car. Could I have used a ‘lighter’ approach…perhaps but I really don’t think a spray sealant would hold up to a Winter where I might not wash the car for 3 months…resulting in this:



Which cleaned up quite nicely & relatively easily once Spring finally showed up. Besides, I’ve always liked coatings; the stainless fridge in my kitchen is coated as is my mailbox because fun is where ya find it.

Thanks for the reply,

He specifically said he wants me to Ceramic Coat it and do whatever I do to my car lol. He has had it washed by professionals and likely decom/washed but as you said if the built in coating to the pff is wearing down he likely wants that back. I mentioned a spray ceramic and hes like I want the Bryan Special whatever you would do to your car haha.

Just wanted to make sure I'm doing correct steps and not using a product I should not be using on PPF but I was pretty sure the products would be fine. As for the APC I have used both but I figured the Gtechniq one would be better to make sure the surface is super clean so it can last as long as possible.

Thanks

Gtechniq revised their panel wipe not long ago and it is not as aggressive as it once was. A regular coating will do just fine. No need to use C2V3 or V4 after coating it. Exo is doing the job.

You could also lightly polish PPF if need be to remove some defects but that will remove the top coat for sure. The top coat will degrade over time.

I would probably stay from Trix as it does contain tarx which can affect adhesive.

Ok so GTechniq W6 Iron and General Fallout Remover it is then.
Not needed but since i would be there i would want to throw some C2V3/4 on it just to add another layer of protection and it only takes a few mins.

Thank you.
