S100 underhood

Is S100 unsafe to use under the hood? It's been a while, but its time to bust out the TA for spring cleaning!
 
Me neither, I just wanted to make sure because I gave the advice to put it under the hood of someone elses car. I figured it would have been fine, but it has been a good 8 months since I detailed my car.
 
I used a spray wax under the hood at a show last year. I was pretty impressed with it. I wouldn't do that as part of my regular detailing routine because I'm sure it would disappear pretty quick with the temperatures under there. Its a good idea for show though I think.

It looked really cool in person. I'm sure its just because the hood is shaded and what it is reflecting is in the sun, but how many times do you see the engine reflecting off the underside of a hood?

I was pretty happy with it. I guess that is what happens when you keep the underside of your hood cleaned often. ;)
 
S100 doesn't seem to last long at all on the outside in normal heat .. prolly least way less in the engine compartment. If you want to do something there get a bottle of Nu-Finish liquid.... cheap and is a ploymer.
 
Same here, i'd use a cheap polymer for such areas, in addition, most underside/hidden panels are not clearcoated so it wont really help much if you use a pure wax
 
Well, I have some Zaino I don't use as much anymore. I mostly use it on my Chrome rims. Would this be OK to use under my hood. I have Z2, which is supposed to be for un-clear coated areas. Will this still work for the un-cleared areas?
 
If the area is uncleared then I don't see what the point of putting a sealant on it would be. Other than maybe making the water bead up on the paint under the hood or something... Its really not going to do an awful lot for unclearcoated surfaces as far as appearance goes. And its not like you have to worry about UV rays or anything like that.... I'm sure you could use it, but I don't really see what the benifet would be.
 
I was just thinking to make it easier to clean when I have to clean it again. I had it lying around and it was just a thought.

I take the opposite view on this one. I polish and then REALLY seal the rough, un-cleared areas, trying to make up for the factory's shortcuts. It keeps these areas cleaner and less likely to retain moisture. Much easier to clean, too, compared to scrubbing stuff out of the rough texture. After a few years, the benefits are much more noticeable than they are at first, cumulative effects and all that.

Yep I'm with you with this.



I plan to seal the underside of my hoods on my Boxster soon. They are non-clear coated and much more diffcult to keep clean.



I'm just trying to work out what to use? Klasse SG? NXT? Blitz? or even Meguiars Engine Kote, because I can spray that on and into the hinges??
 
JB in Irvine- I wouldn't use EK; for one thing, I'd be worried about making a mess. I just use whatever seems easiest while still giving decent results, which is usually the same stuff as I'm using on the outside. This is one application where ease-of-use can really make a difference, but then all the stuff I use these days is pretty user-friendly.
