I am thinking about buying a compressor & a shot/grit blaster so I can give the nearside rear wheel arch & some of the seams on my van a good blasting. If I can get it back to clean metal & treat it with the correct stuff it should keep the dreaded tin worm at bay for a year or so.

I have read of some posts from a year ago regarding compressors & apparently if you are ever going to consider spraying a vehicle in the future you need a compressor which holds at least 50 litres of air. A suitable one could cost at least £250 - £270 plus the cost of the shot blast gun ie. £39 - £69 & of course an air line @ £20 -£30. There are various othe ratings such as 'free air per minute' to take into account. Some compressors are direct drive & some are belt drive but I don't know which is best. Maybe someone can enlighten us?

The free air displacement (cfm) is perhaps the most important figure to consider when buying a compressor. A big tank is useful, but will soon empty if the compressor can't keep up. Belt drive compressors are quieter and last longer, but tend to be more bulky.

I have a huge 200 litre Sealey in the back of my garage, for use with air tools & spraying. That's 14cfm, 3Hp. Outside, in a secure locker, I have a pair of Clarke Tiger 8/35s connected together. (They're outside so that my airfed spray mask doesn't poison me!). The little Tigers will cope with most jobs, but they struggle to keep up with spraying and certain air tools, like the nibbler & orbital sander, just won't run from them.

Machine Mart used to have a decent 12cfm compressor at a reasonable price, but that seems to be NLA. I must say that I wouldn't buy anything less than 10cfm now. But don't dismiss compressors out of hand on price alone; there are good second hand bargains to be found (my Sealey came via ebay), and one you've used air tools you'll wonder what you did without them!
