back in the day......when everybody did it with paint.......choices were 1-SHOT/RONAN POSTER PAINT for short term or regular 1-SHOT/RONAN for stuff you wanted for more then 2-3 months.
the old paints you could get a solid cover with and those that didnt we added a few drops of silver/aluminum paint to the colors. now all the FLOURECENT COLORS.... you had to apply a white background........cause the pop of the color wouldnt show up without it.
i preferred KILZ...........for background. dried quick and covered with a roller well. and when i got done with graphic, i could immediately take a razor blade to the KILZ that was outside the graphics......quickly and ease.
you can use latex..........gloss i preferred.... just looked better.
this is all 1-SHOT except for the green words on the bottom.........was done in 2000..........and is still on one of the 2 windows i did........
IF YOU WOULD LOOK AT this guys work.........you will see how a pro does it.....and iam sure if you had any questions he is a nice guy and would tell you what you need....
