How about appearance. Does it stay clear?
Also, is it very important to get the Dow Corning 995 anchoring glaze? They don't have it in clear, for some reason. How bad are the fumes on that? I have a little emphasema and I noticed that the product has some warnings about hazardous vapors.
How long do the vapors last?
Also, is there much difference between the brands, like Llumar, Armorcoat, 3M?
Any info would be appreciated.
