Well, I mentioned this product in a couple of threads and thought I would share my experiences.
There are several relatively new nano-sealants and permanent coatings that have been attracting attention in the detailing community especially in the last year. This particular product is from G/Techniq and is called C4 Permanent Trim Restorer. They say "permanent" but in actuality is really a semi-permanent coating that they claim will last up to two years. At about $50 for 20ml, it's not exactly cheap but even if it only lasts 6-12 months of the claimed 24, I will be satisfied.
I decided a couple of weeks ago to go ahead and apply C4 to a couple of areas on the wife's (or DD) 2008 Forester. For those that may be interested in this product, here are a couple of pictures and my initial impressions....
Cowl before:
Cowl 50/50 (including wiper arm):
Rear bumper guard before (with flash):

Rear bumper guard after (with flash):
Rear bumper guard after (no flash):
Rear Bumper after (with flash....lower trim also has C4 applied):
Rear Bumper after (no flash):
The car hadn't been washed for a week so I did a quick clean up of the pieces I applied the C4 to which included a thorough wipe down with IPA. The wiper arm needed restoration IMO before application of the C4 but I was running out of time and just wanted to get the product on these bits before the wife needed to take the car.
Application is very easy with the supplied applicators (they look like little, round, cotton make up removers.....shown in the 2nd pic). Tight crevices, ridges, etc. (like the Forester lettering on the rear bumper guard) are easily reached with a cotton swab. After application I gently wiped the areas immediately after with an MF towel as per the instructions. The finish is satin-like with a little more sheen than I probably would want but if this stuff lasts the 1-2 years they say it does, I think it's worth it. I also applied C4 to the rocker panels, rear apron, chin spoiler, tail light and front grille surround of my 2010 Challenger R/T. I was planning on finishing the cowl and will add pics of that.
I'll try to post updates as time goes by. I'm really hoping this product lives up to the hype and will keep its finish as the months pass. In the meantime, here a couple of pictures to show the beading characteristics of the C4 on the plastic bits I applied it to (snapped these after I washed the wife's car last weekend). While I don't take this beading as any sort of meaningful indicator at this point, I thought I could use it as a base line for future follow ups. ....FWIW:
