Questions on lettering glass

I was curious to know if anyone out there who has painted on glass. I am looking for the right paint to paint on glass, as far as lettering it for on a car lot.
I tried to use this one product but it fades fast and brush strokes are always there.

 

White shoe polish for that ol skool look. go to office supply or an art supply store for those neon colors you see on dealer lots.

 

look into window splash ...(pretty sure thats what this is called) .... last windows i lettered ...used white for the base.....and went from there......there are a couple window guys in my area......they do some cool stuff.....brandon

 

window splash works best, will last the longest and razor blade right off.

 

You can use Sign Painters 1Shot! It's a 'lil tricky on account the surface is so slick.
