Sounds like you have a plan Jim, if there’s any insights or knowledge I can provide from 40 years of spraying feel free to ask. I can tell you that I chose to take mine off the rotisserie and put back on my casters since I had sprayed all the insides and underneath and would not need to spin the car to do any of that. Other reasons were on the rotisserie it was pretty high and would make the roof a real nasty reach and with my telescoping casters I could lower it down to a nice comfortable hight and messing around spinning the car while your trying to not stir crap up and the paint is flashing and you don’t want to lose your wet edge and this being your first time it could be overwhelming. I know many guys would like to spray their own cars but I think you need to consider if it makes sense with all the hours of labour that it took to get to the paint stage and some expensive paint and risk a result that could be pretty disappointing. I did a ton of small jobs to gain some feel for it before my mentor allowed me to tackle a complete car which was the correct decision and I had a nice result, there’s a fair bit of skill and equipevent involved. I always incourage someone that wants to give it a try to get a panel or two damaged panels and try it out on them to get a sense of how the paint flows and how fast it flashes off. What ever route you choose again feel free to ask if you would like my opinion. Cheers brother.
