If you're going to go through the trouble of dis-assembling your bike, spend a few extra bucks and get it powdercoated. The benefits far outweigh the costs. However, if you do the prep work, sand, thin coats, etc...you should be able to achieve good results at home. Not as good as the powdercoat job, but still respectable and for a fraction of the cost. SO, if you're short on money or long on time, the spray can technique or even HVLP technique will work fine. Good luck!
