detailing and engine compartment

[BlakeP69Z28]

i have pulled the motor, found the correct distributor and i was fortunate enough that the car came with the original carb in a box in the trunk. Jerry Mcneish redid a stellar job on the renovation of the carb and distributor. My question is i have removed as much of the old paint on the fender wells, subframe and radiator wall.

i have 150 psi capacity air capacity with a 2hp motor and a 29 gal tanki, i have tried walnut shells on practice items and they seem to fine but jam often,to often.

I have the engine bay so stripped down i don't want to stop now and then paint it, the nooks and corners are hard to get it complete and I thought sand blasting with walnut shells would help me get the rest of the way. i am really close to getting it dialed in.

then i have a question does a air gun doing the painting make it that much better versus rattle can and should i use a primer first? any input would be appreciated.

thanks in advance,
