Hey, old Friend !
Have not seen you on here for awhile !
Glad to see your dd1101 again !
Well, as you know, there are a few coatings out here now, compared to the days when Zaino was the precursor and only one that was years ahead of its time...
I have not used Gtechniq but have not read very favorable reviews about it either..
The hottest most talked about coating is Car-Pro's at the moment, I believe...
The most durable coating and what I put on all 4 of my vehicles over 3 years ago, is Optimum Opti-Guard, now Opti-Coat Pro, and I am so glad I did it but wish I had done it sooner.. This stuff rocks !
No Coating except for a good Clear Bra is ever going to prevent rocks from chipping paintwork.. Its a few microns thick at best while a clearbra is many more and more durable.
Perhaps a coating might help prevent an object from taking paint off a little, if its slick enough perhaps to help deflect a flying object from taking a full direct hit on your paint, but no one has ever really tested this that I know of..
Then there is the opinions on which coating has the most Gloss over the others and it goes on from there...
So, once you decide what you want to get out of any Coating, you can then look at the ones available today and narrow it down further..
Since all of the appearances of anything put on paintwork is so subjective, it would be really hard for me to want to say that this coating is glossier than that one always, etc., so Im not even going there..
I can just tell you that my 3+ year old Optimum Opti-Guard is going strong, looks amazing to me when I wash it (which is very infrequently), is extremely clear and glossy to me, and has very little if any scratches in it after all this time...
I do not do Anything to it between infrequent washes, dont put any toppers on it, and there is no "regeneration", etc., products that are suggested to apply to "renew", etc., it..
I wash it with Car Pro Reset car wash soap which came out recently and is made for washing coated paint.. It seems to leave the finish really smoother compared to other soaps I have used that had things in them..
I am not even sure how long it will last, but I heard once that Optimum had it still on their test vehicles some 7 years hence.. I have not had time to verify this...
Its been so long that it came out, I think that perhaps David Fermani might have been involved with this way back then??
Good luck with your research !
