I used this gun to varnish shelves. I have taken time to understand the operation, not the package leaflet being obscure but because the varnish was drying too quickly and obstructing the holes. You have to think thoroughly clean the nozzle to avoid that, and a little dilute the varnish as shown. Once I am upset over, I finally got the gear that is quite up to par. I will then use it to polish my garden furniture.
