engine re-paint, silver

[red98]

The silver paint on my thou's engine is flaking bad, ive just replaced the fork seals so thought it a good time to sort the flakey paint out, forks off the bike so I can easily get to the front of the engine, started dismantling at the weekend, exhaust, radiator, oil filter +oil , clutch cover, generator cover and timing cover, going to blast the three covers as they are quite bad and are the first thing you see, will paint them off the bike and refit with new gaskets, front of the engine I will attack with gunk and a selection of wire brushes, a lot of it will be hidden by the rad and exhaust but it looks awful  :eek....I bought a blast gun years ago but my compressor is not quite man enough to power it, got loads of air at work, most of it hot  :rolleyes and the boss is away untill next week, guess what iam doing friday 

so, anyone else done this job ?.or got any tips ?...
