Just a mention that I don't quite get this one. Spray tip sizes are almost always sized starting with 80 (the degree of the fan "spread") followed by the output the most common are 80/30, 80/50 and 80/70.
While and 80/20 is made they will clog easily with sealer and are usually used for primer or other "water thin" materials. (80/30 will clog easily if you use a good amount of sand) so 80/70 puts out sealer pretty fast and is better for larger areas (they make an 80/100 but it's VERY hard to walk fast enough for them, they are usually only used for very thick sealer or very hi-output units like spraybars on hi-powered pumps) so the most common tip for driveways is the 80/50 for a large enough size to not clog and a moderate output that's still easy to control in tight spaces. If you have careful employees or handle the wand yourself the USA Tips ceramic tips make a beautiful, even spray fan without the thick & thin spots of some steel tips and wear a long time. The fans are beautiful so the application is more even and control is easier. The only downside is if someone drops the wand directly on the tip they can break--they are not terribly fragile but if people are used to tossing steel around they will break them.

this is not for a spray tip but angle on wand

In that case if you use a 45 you will need to do some fancy maneuvering since the spay tip must always be at 90 degrees to the surface for a uniform coating. Would seem much easier to use the 90 and not have to worry so about wand position.
