i just did my black truck with klasse since i got home after 5pm,the klasse havent been buff off(it gets dark now here in maryland at 5 pm,my garage is not well lighted)how long can you let it stay in the car?will it damage?caked?its been 2-3 nites now

and why do you need to buff it off everytime you add a layer,can you just keep applying until you got 3-4coats of the product?guys need heelp pls. enlighten me....later
 
andy, you can keep it on there as long as you like. I tend to take it off before the night ends because when you do the final buff a day or two layer you have to buff off all the dust that lands on that surface too.



as for just applying right over the SG, I would think that SG in solid form as a haze that is not on the clearcoat might hinder the next coats ability to stick to previous layer, just a speculation though. maybe the solvents will cause the solid SG to go back into the solution. I guess that answer to that question is, you try it and tell us what you get. :)
 
I agree with Steve, you can leave AIO on as long as you like (just keep it out of the sun). As for applying KSG over AIO, its not really meant to be applied over top of the AIO residue, but hey, try it if you want, and if you do let us know how you make out.
 
I did try the SG right over the top of the AIO. Kind of like the Blitz concours application method. Leaves a great awesome shine. I was just worried that the SG wasn't bonding to the car properly. I also tried mixing a little SG with AIO and that also seems to work real well. Leaves a better shine than just with plain AIO. I guess this would be good for someone in a hurry but not for someone looking for the ultimate shine.
 
Some vehicles, such as GM cars have clear-coated headlights, which are very difficult to polish and restore, once they "fog" or yellow.

Wet sanding and polishing does work, but they never look as good as the non-clear-coated ones.

Can that old frosty clearcoat be removed safely, without damaging the headlight lens???
 
You can always just wait for the oxidation to totally take over and it will start flaking off all by itself!:D

The lenses on my 97' TL were heavily oxidized and flaking at the top, so I wetsanded that part and then polished the entire lens until it just blended with the still clearcoated part of the lens. When I look at it now, I can't even tell where the parts of the uncoated lenses are.

I read on another forum where this guy, after wetsanding and polishing the lens, coated the lens with a 1:1 mixture of mineral spirits and Helmsman Spar varnish. The results were very impressive. I'll be trying that out on the Acura soon.

That's the technique I normally use. But the non-cleared lenses are SO much easier to and they always look better when finished.

Maybe I'll try to get a couple old nasty lenses from a salvage yard and experiment with some different paint strippers and see their effect on the plastic. (Retired guys need to invent things like this to occupy their time!):biggrin:
