If you are spraying, grit blasting, etc., also go for at least something like this https://www.ebay.co.uk/itm/315161340010?var=0&mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338268676&toolid=10044&customid=EAIaIQobChMIuKPUpt_YhQMV_5lQBh2t5AmyEAQYBCABEgLdKPD_BwE I found they work surprisingly well at removing moisture from the compressed air.

+ 1. Really, go for the larger one. I used to have a small one but you need the umph even for spraying and just about everything else.

I have a 200l tank one. Really worth it. I bought mine from https://www.sgs-engineering.com/ and have bought several tools from them. Nice company to deal with.
