Painting Clutch Casing advice

[gel]

Thanks for the feedback, I was going to pray it in the garage (warm and dry and no wind). How difficult is it to refit the clutch cover as I have been told the clutch actuator arm is difficult to refit. There is no pitting in the casing to I am hoping I will not need the P38. I have bought aerosols, so possibly a mistake, oh well! so do I need a primer? 

thanks once again
