Want to Apply Coating but Rain in Forecast...

Need some advice. Bought Gyeon Prime and have never used a coating before. I`m not anticipating any issues with the application process, but am concerned about possible water spotting once it is applied. I`ll wash, decon, clay, and polish today, then wipedown with Gyeon Prep and apply per instructions. The car is garaged, and will stay in garage during process and initial curing, but its supposed to rain here on Saturday and I might need to drive in the rain at some point. It will be able to cure for 24-36 hours before seeing any rain, but I am concerned with things I`ve read about water spotting issues in the first couple weeks after application.

Normally here in SoCal three weeks without rain is the norm, actually 6 months without rain is the norm, but the freak occurrence of rain is going to coincide with the time off that I have from work for the next few days. If I go out in the rain I`ll dry it as soon as its back in the garage so water won`t dry on it, but will exposure to water 24-36 hours after application cause issues?
 
Could you wait until you coat it? I am in the same position as you. I am waiting it out until more days of the typical sunny So Cal weather. Maybe just wax it or seal it for now.
 
:rofl

Darn this crazy So Cal rain!! Same boat here. Was trying to plan a coating job on my daily driver around a trip to Legoland last Monday. I figured I can coat it in the morning, and stick in the garage while we take the wife`s car for the all day trip.

I`m pushing it back to the upcoming Monday. [sigh]

I can definitely wait. No urgency, its wearing FK1000P now. I just wanted to play with a coating. I`ll be getting a new car in the next couple months so I wanted to apply a coating to this one in order to get some experience with the product and process. No real down side since I`ll be getting rid of the car soon...it can be a rolling collection of test panels for now.

Thanks for the input guys. I guess I`ll just wash it, do the interior and then watch a lot of college football over the next couple days.
 
Gyeon Cure was designed to help with lowering the chance of water spots...

PREVENTS WATERSPOTS AND STAINS
 For the first couple of weeks following application, quartz coatings exhibit a insignificant tendency to develop hard water stain deposits. The use of Q2M Cure immediately after the base coating application will help eliminate that risk entirely. The product is also amazing as a Quick Detailer, removing all potential streaks and residual water. It gives the paint a vivid shine, restoring the "just after coating" appearance.

GYEON Q2M Cure - 400 ml

I`m guessing you got the kit with the cure in it


I say if you`re going to be testing stuff anyways, and considering you plan on getting rid of the vehicle soon...go ahead and coat it...hell, coat a fender and then get it wet sooner than recommended...see what it does, how it plays in those scenarios so if you ever come across this again you`ll know

that`s just how I`d approach it personally
 
The text you quoted is actually what prompted my question. "For the first couple of weeks following application, quartz coatings exhibit a insignificant tendency to develop hard water stain deposits. The use of Q2M Cure immediately after the base coating application will help eliminate that risk entirely."

It seems to be a translation from Korean, and I`m probably taking it a bit too literally. I don`t know what an "insignificant tendency" is. Especially when the next sentence speaks to the need to "eliminate that risk...". If its truly insignificant then it`s irrelevant and doesn`t bear mentioning, and it certainly wouldn`t be considered a "risk." Either its a "risk" or it isn`t. "Insignificant" implies that it isn`t a risk, but the recommendation to use a separate product means there is a risk worth avoiding.

Second observation is that the directions say that after applying "a thick layer" of product, "wipe off immediately (10 sec - 2 min) after applying on the whole panel/section." Ten seconds is an extremely small window. But this is why I want to play with it. Most comments on this product on the forums say that the time is more in the couple minutes range depending on temp and humidity factors. We`ll see, I`ll have fun with it.
 
There was recently an article on DI just published. How To: Protect Your Paint with Gyeon Quartz Q2 Mohs | Ask a Pro Blog

Grabbed an excerpt from it about the application and curing timing:

Mohs has a very fast initial bond with the paint. You can begin to remove excess product between 30-45 seconds after application, and up to 2 minutes. At the 30-45 seconds the product is very easy to remove. It may begin to tack up closer to the 2 minute mark. It is this quick initial bond that makes the product extremely easy to use. Use a light during this stage as well to help with product removal.
Mohs can be layered. 2 layers is typical with 3 layers being the maximum. You want to wait at least one hour before applying each layer of product.
Keep the freshly coated surface dry for the first 24 hours to allow the coating to cure and do not wash with any detergents for 1 week.

 
Wipe it down with cure before you take it out, when you come back you can blow it off or spray some cure on a damp micro towel,wipe it off and follow with a dry towel with a single spray of cure per panel. After 3 years of doing Gyeon I`ve never had a spotting problem even on non garage kept cars
