Gtechniq Platinum - 18 months on - How do I restore the just applied finish?

Hi there,

I have a Porsche Cayman R which had the Platinum package applied by the dealer (RPM Technik) at time of purchase. Its so far done a reasonable job of keeping the car nice even though it lives outside.
Ive washed it weekly using Gwash and it gets regularly topped up with C2V3, and on the whole it always looks nice.

However i feel the paint could be getting a bit grubby now and doesnt feel as slick or as glossy as it used to.
I have so far avoided the use of EXO etc as i read that it needs to be done in a temp controlled environment and away from sources of moisture for 24 hours etc. As said, the car lives outside so this is not an option for me.
My other cars ive always machine polished myself and treated with non ceramic type products and had good results. However im at a bit of a loss with the Porsche as i want it to look amazing but im frightened of messing up the coating.

What can i do to revive the look of the car and give it back that super slick gloss and hydrophobic "just waxed" performance?


Much appreciated

Frayz

The Platinum protection is supposedly a 5yr warranty, so i'd be going back to RPM for advice as well.

It doesn't detail what products are used in the package but with that warranty i assume its the crystal serum topped with exo ??

Exo in itself is not a 5yr product, its a hydrophobicity enhancer.

what wash product have you been using, and any after wash products applied like quick detailers ?

If you've used quick detailers, sealants or waxes over the ceramic then at the very least you'll need to remove such products and de clog the ceramic layer, with a thorough wash with W5/W6.

Have you tried calling Gtechniq ?

Washed with G wash and then just topped/dried with C2V3.
Never put anything else on it.

You are seeing the water behaviour of C2V3 then, and not that of EXO. whether you can directly reapply EXO to what you have now will have to be guided by Gtechniq

Yeah i think so. Im seeing more C2V3 than EXO.
Paint just feels like it maybe needs a clay and deep clean without messing up the coating.

Gtechnic Platinum is a dealership only applied product, and is designed to sit between C1 and CSL. Training and support is given by the REEP Group and not GTechniq

If the coating is a bit grabby, try GTechniq's fallout remover and Citrus APC through a lance to deep clean the surface of the coating, you could also try CarPro Reset shampoo too as this is designed with deep cleaning in mind on coated surfaces.

If that doesn't work - take it back to the company that coated it and ask for further support as that really is what they are their for

G-wash is ok for maintenance but sometimes you need to give the surface a deep clean and that called for something with more power. I would recommend using CarPro Reset as this will help rejuvinate the coating and also remove any light contamination present.

If the contamination is heavy then it might need a claybar treatment, a mild bar or mitt should do the job, just use plenty of lubricant to ensure there's little or no marring. It won't strip the Platinum but you will have to re-apply the C2v3 afterwards.

Thnak you chaps.

It has not been used at all throughout the winter as i will not drive it in salty conditions. Not to mention its on Michelin Cup2 tyres which are bum clenching in the wet at best haha.
I will try the Citrus cleaner and Iron/fallout remover first.

Is the Carpro reset an all in one cleaner and better than the above?

Thanks again
