If you priced out a good "rattle can" DIY paint job and paid yourself for labor, you'd be very close to the cost of a proffesional job.
I'm finishing up my Norton paint as we speak. I'm not a pro, but I do have a lot of experience with paint and rattle cans.
Here is a quick workup:
Interior tank prep:
Evaporust: $25.00
Acetone & MEK: $10.00
roofing nails: $10.00
P.O.R. Prep & Ready: $35.00
Caswell liner: $40.00
4 hrs labor @ $50 hr: $200.00
Total interior Prep Cost...... $320.00
Exterior finishing:
paint stripper: $10.00
sand papper: $20.00
body filler: $20.00
Primers, etching, filler, sandable & sealer (Duplicolor) $30.00
Gold undercoat - for striping and logo (Duplicolor) $20.00
Base coat (aerosol cans from automotive paint house) $90.00
Clear coat (SprayMax 2K) $100.00
decals-used for stencils and masking tape: $20.00
10 hrs labor @ $50hr: $500.
Total exterior finish........$810.00
So for a "rattle can" paint job, I've got about $1130.00 into it. albeit I have some leftover material.
but then again, I know the right way to do things and as mentioned have experience painting. IMHO, I have done my own pro job. My last Norton tank I did in the mid 80's is still very much alive last I saw of it when I sold that bike in 2002. The one I'm doing now should last as long, if not longer as the materials I'm using are much better than what was available then.
I agree with the other poster, if your going to do it, do it right the first time, and it WILL last.. Unless youget it right, you can expect to have a few "do-overs", plus the added time and cost for those do-overs.
It's a learning experience. Or if you don't have the time, it's about the same cost as farming out the job to a pro.
