Venmo @John-Burbidge-3 to buy me a beer for making these free videos. Thx! 🙂 John Burbidge, author of the book “Watching Paint Dry,” demonstrates how to use a paint sprayer.

Update 2013: There are some homeowner-grade airless sprayers on the market these days that do not require throat seal. Consult your owner’s manual.
