Apply another coat of sealant after another?

I didn't say that nobody puts a second coat on just to be thorough. I said that I doubted that many people did that. If someone just spent five or six hours detailing their car and are tired enough that they missed a spot, they probably aren't going to have the energy to put a second coat on. In fact, that is the situation that is perfect for putting a second coat on after the 12 hour cure time.

If anyone feels that what I said was being argumentitive then that is something I can't control. I never said that I don't make mistakes. I do advocate following the directions from the chemist when it comes to certian products and I am against the proliferation of short cuts as best practices. Sealants need cure time before any other layers are put on. The product doesn't care if you are being thorough with a second coat or if you are trying to short cut the cure time. If you miss a spot with a sealant then you should look around the car for them before you buff the product off so that you don't impact the cure time. Everybody misses spots, but that is what second and third coats are for. You really aren't going to be able to tell if one spot has two coats and another has three. Your paint isn't going to notice either I'd wager.

So anyway, I'm not trying to be argumentitive here. If someone has a problem with how I write, then I'm sorry for that. I'm only trying to help, but it seems that there are always individuals who are going to take offense where none is intended. My goal isn't to go around offending people, but anyone who knows me knows that I don't sugar coat my opinions or feelings. If someone stands opposite of one of my opinions then join the club. We are all operating under different schools of thoughts about detailing. As Aristotle said, "It is the mark of an educated mind to entertain a thought without accepting it." If the process is contrary to the recomended use from the manufactuer then you can bet I'll call you on it. If it is just a matter of opinion for how it is used, then I might ask questions or share my thoughts, but I respect the processes of others as long as they aren't going against the way things are supposed to be. Messing with a sealant layer before it is cured is one of those things. If it was wax we were talking about then I wouldn't have said anything since it doesn't matter as much. Sealants are a different thing though. I wish some product gurus would pipe up here and tell me to shut up if I'm wrong about this. I don't like feeling like I have to defend what I presumed was an understood fact about a product.

Since the curing time for sealants is anywhere from 12-72 hours, then adding a second coat to make sure coverage is complete can not be a bad thing. Yes it would really be making one thicker coat, not two coats as the sealant has not really set itself up yet, but I believe that two overlapping coats are better than one, especially if you are doing a customer's car and you won't be able to add a second coat after the first is fully cured ...
