If you've ever had a situation where you wanted to spray a little bit of polyester resin, but either didn't want to use a good spray gun or didn't have one to use, this little unit is great.
It uses a disposable paper cup, so there isn't that sticky resin clean up to deal with. (Just the front plate and nozzle need to be cleaned) Just mix your resin or gel coat in the paper cup, attach to the spray unit, hook up your air hose and spray. Will also spray some rubber materials and plaster with various nozzles available.
