Sadly, I do not think the finished paintwork is of a high quality that I would use it again... with practise it could come out 'ok' but, I need something better like my old compressor that I sold and now? I'll be buying a 50L compressor knowing that the professional finish I need will be delivered each time, as with a compressor. The PSI is only something like 4.5-ish, NOT powerful enough and, once again... sorry!
With a lot of practise I guess you could get a reasonable finish... but, I don't want to waste anymore time on this. I phoned the manufacture's of this, Sealey, and they promised to call me back with some info and? Nothing, so it seems they are not bothered.
Would be ok for spraying a shed but not good for internal decor all paint used needs to be watered down significantly. No control over the air pressure .
