SG question....Wipe on wipe off or 24 hr cure

Guys,

My new toys are going to get here on monday or tuesday and I was wondering why some people use the wipe on wipe off method for SG and why some use the 24 hr cure time.



Which do you use and why?



Also, If I were to use the wipe on wipe off method, would I still have to wait 24 hours before applying another layer of SG?



Thanks for the help and if anyone would like to add anything on their experiences or anything on SG feel free to say so.



Jason
 
Also, not everyone can let their car sit for 24hrs straight, so thats where the WOO method comes in... (or WOWO same thing... I like WOO)



so after a day of driving you can come home and qd/s&w/wash and then add another coat.
 
A product curing is different then normal solvent drying. When you take a product off it's because the solvents dried and left the sealant on the paint, but the sealant hasn't cured yet. If you wipe more product on the solvents and active products will effect the sealant that is on the vehicle. Think about basic chemistry, like attracks like. However, when the product itself cures (all solvents are not present and the sealant itself has crosslinked or fully dried) you can put your next coat on. That's a good product choice and a lot of people get good results with 24 hour cures but I would wait 2 or 3 days between coats. And the manufactorer recommends a week between coats for best results. One coat of that on top of a coat of AIO is a pretty good protected surface anyhow. They do have instant cure products out there but that's not one of them. When I use SG I use WOWO. It's a finiky product and I like to get it off right away. Always have AIO handy if there's any problems. Once you get it done it leaves a very nice finish.
 
Thanks. So you mean instead of letting it cure for 24 hours and then buffing it out you just put it on a panel, and buff it out of that panel then go to the rest of your car?





Why would you wait 24 hours when you could just do that if I am getting what WOWO means?
 
Man, I must be really misunderstanding here. If I were to put on ONE coat of SG then want to top it with P21S how long would it be until I could put that P21S on using any method that is shorter?





Sorry for the q's, I've almost got it.

Just personal preference.



I find that the wipe it on/let it sit/wipe it off the next day is a) *very* easy, almost effortless, with no problems of any kind and b) more convenient *for me* as I only have to spend a little while putting it on and then a little time the next day taking it off. FWIW, I only use SG on our minivan, and by the time I wash/dry it (I really *do* the undercarriage, etc. every time) and put on the SG I've had enough for one session. When I'm doing polishing and AIO too, it's a pretty big job and after putting on the SG I'm at a good stopping point. The wipe-off the next day couldn't be easier and, well, I just like splitting it up that way. Sometimes I just let it set up for a few hours, depends on what I feel like doing. Sometimes I let it set up for more than a day (yeah, it stays clean in my garage).



It seems that the longer SG sets up before wipe-off (I've gone as long as four days), the easier that wipe-off is. Not that it's ever tough or anything, but there is a difference.



I've tried the w-o-w-o (I do use that method on black plastic trim) and I just don't like doing it that way. Nothing *wrong* with that method, but it's not what I prefer. IMO everyone should do whatever they enjoy doing, as long as there's no (functional) problem with their chosen method.

No matter how you do the SG, wait 24 hours or so before you top it with the wax.
 
Apply, then buff out the next day. Sounds good.





And P21S is called what at Harley Davidson shops that I can buy? S100? And I will post pics once I do it.

Yep, that's it. But I wouldn't be in a hurry to top the SG, more layers is better ;)



If you're buying wax anyhow, give some thought to getting Meg's #16 instead. Some of us like it better than the P21S/S100. Similar look, better beading, better durability. Cheap too, since a can will literally last for years.
 
It will really look as good as S100? Because I love Meguiars stuff, maybe I will go that route. Similar results?





I hope so. I may only have time for one coat of each. will that still look good or am I better off just doing one coat of NXT after a wash with nothing under it ;)

First response and IMO, Pat nailed it. The only thing I can add is that I would wait a full week after your last layer of SG to top with a carnauba (if you so desire).

Opinions differ, but I consider the #16 about the same looks-wise as the P21S. Sure doesn't look bad. If you only have time for one coat, it'll give you a lot more protection.
 
I always assume it starts when you apply it; when you wipe it off you're removing "excess" product that hasn't bonded to the paint or otherwise contributed anything and the SG that stays on the paint is already "set".



When I layer the SG on our vehicles *using this assumption* it lasts an incredibly long time, far longer than it coud if each layer was removing the preceding one. I've been doing this for years, so I'm pretty confident that I'm not wrong about this ;)



But if you applied the SG *so thick* that it couldn't really cure "properly" (and I mean goofy-thick), that could change things. So put it on as thinly as you can and you should be fine.



Oh, and I've read that a longer cure time (e.g., a week or so) is better than 24 hours. Could be, but again, I'm not experiencing anything that indicates that the 24 hours (after initial application) is insufficient. Still, I always layer some more on after subsequent washes, which is probably a good idea if you're going for maximum durability.
 
I just bought some AIO and SG from the autopia store! I also ordered #16 from the Meguiars site.





I am really excited to get started with this stuff. Thanks for guiding me everybody. I hope the stuff gets here quickly even though I ordered ground shipping...
 
When i detailed my car last i used aio and sg. After removing the sg i applied NXT, which after reading this thread, i assume is a bad idea. Can i apply a wax over sg after just having removed it? I'm asking this because a lot of times I only have one day to do a complete detail on certain cars.
