I think I get the 'drift' out of what you all have said and it comes into my direction of thought.
The book I will order and see what I can learn from it. Interestingly, I was brought-up by a father who requested the parts book when he ordered a new machine, tractor etc. and I recall one instance when the seller (in does olden-days, the owner of the company) sent the manual. My dad went ballistic and told the good man 'how can I know how the parts in the machine work together if I don't know how they are put together' and that is exactly true. Well, today nobody once you to know how everything works together, cause people without knowledge are easier to herd.
Powder-coating struck me the first time my oldest had everything build for our oven and put charge to a build piece of steel, sand blasted and clean as can be, washed and 'gased-off', stuck the primer powder on & backed it, pulled it out and sprayed the actual color on, backed it again, pulled it out and clear coated it and backed again and after letting it cool the part went into whatever it was made for. No day to wait for it to dry or the scare to touch it to put finger marks on.
But I get your drift (again) and will do it for the frame, because once sandblasted (with low pressure and fine grid sand) the whole frame can be nicely done. Some structural parts we will do ourselves (powder coat) the rest will be sprayed. My son has what Kevin mentioned, a 3M accuspray. Not sure if he let's me use it, I doubt it, but I have seen the advantage of the system, particularly for smaller amounts to be sprayed and will invest in one myself to get this right.
LOTS to LEARN, AGAIN.
