This is Bruce from Trusco Mfg.
If all you are doing is Handicap Spots. All you need is a roller with a long handle. Or if you will be doing a lot of them you could get a airless sprayer from Home Depot ($50 or $100) and make cut out your own stencil from cardboard or plastic?
Our equipment is designed for lining parking lots. We have a Hand Wand Attachment for spraying arrows, HC Spots, etc.
If you get into the striping business we have a good machine. They work very well!
E-mail me if you have any questions trusco@atlantic.net .
