This item was well packed and delivered quickly. The instructions were easy to understand, but I was disappointed not to find a list of approved paint. As I had eighteen doors to paint in undercoat and gloss white, I needed to get it right first time! I was informed that water based paint was easier than oil based to spray and that it would be easier to clean up afterwards, so I used EcoSure from Dulux. I thinned the paint as instructed, had a little practice on some waste board and as it all seemed straight forward I pushed on with the job in hand, BIG MISTAKE. I checked each door after spraying, but after completing four doors I noticed the paint on the first door was beginning to run and then got steadily worse. Yes I had to stop, sand these doors down and start again. Despite the early mishap I soon got the knack and achieved a lovely result and quickly. I found the spray gun easy to clean and it also seems quite durable. Please note however I would only use this machine in the garage or in a room that is being decorated. The spray seems to go everywhere so be warned!
