Hi there,

Not used both products but have been doing a fair amount of reading in the last month and have decided to go with Gtechniq for my car. I will list the reasons but it must be considered as a biased opinion now

- Long lasting (cs ultra is claimed for 9 years but sold only to accredited professionals). Take this with a pinch of salt sure but see below.
- genuine >3 year lasting base coats ( cs light ) and 2-3 yr top coats ( exo v4), if maintained reasonably . These come with extremely good water beading properties. Verified by users online and also a few users here
- very high gloss and clarity ( note that this significantly depends on paint prep and polish, but the coat will preserve it)
- hardness of ultra is a step higher (10H) compared to 9H hardness of most other films. Still only incrementally harder than the factory clear coat, so while this is nice, it is not a big factor for me- but combined with other factors, lends credence to their lifetime ratings.
- Relatively more direct about limitations and lifetime ratings in their website. They will tell on their site if their lacquers/coatings last only for 2 years or even 3months. their website is one of the few that provides hardcore info upfront in the form of material data sheets. They also provide a very good service cost estimator on their website which makes it easy to check with detailers.

Minimal gotchas on 9 year warranty -if you go with cs ultra: donít run it through harsh car washes, spritz it with a detailing spray once or twice a year and get it inspected also once a year . Reasonable for me but ymmv of course.

The product is good, but you need to find a good installer as well , which is also crucial. Look up the gtechniq website for credited installers if you like.

I have come to like them , but not affiliated in any way. Will be getting my car done in early to mid April and can share pics then.

What is your car color BTW?
