I just learned,by axident"of corse" that when using "filler Primer" in a spray can, that the tip always gets cloged. Also the tip dosen't let you put down as mush at a time as a gun will. To make better. use a tip from a brake cleaner can, or some large carb cleaner cans. The orface is bigger. Less overspray. more primer on whatever you are spraying. Just remember to move faster so it won't run. BuickSmith:blast:
