Chassis painting advice

Im about to spray my 37 Ford custom chassis with base clear and worried that the clear might dry too fast while spraying, leaving over-spray on areas, as the chassis is time consuming to paint. I have the chassis on a rotisserie, so could have a helper turning it as I go, but not sure that will be enough. I haven't painted a chassis before and I'm trying for a "show" finish. Any advice on how to avoid this over-spray? i don't think the base will be a problem in itself. Thanks, Bill
 
use the very slow activator and adjust your gun really well. you want to build the clear by dusting. if you try to hose it on you will have trouble going back and hitting dry spots. remember the bottom is the part that will be seen .
 
Also you could get a quart of retarder and add only as you see you need it to the clear.
 
I was leery of recommending retarder in November, but if the boss says its OK, then that is probably the best thing to use. But overspray absorption might be better than you think, don't dump a lot into the first coat! Put a little in the first coat and see how it handles going around. You might not need that much if inspection shows no dry spray.
 
Sometimes I turn down the fluid, narrow the fan, and reduce the air pressure for the really had to get areas. I just take my time - spraying and looking from every possible angle. After all the hard stuff is done, then I turn the gun back up to normal and go over the whole thing.
 
Thanks for the advice. I may try a bit of retarder. Our winter temperatures don't get that cold, but can often be in the 40's and even in the high 30's. We're in the banana belt for Canada. It's rare for us to get below freezing for any length of time, although about once every 20 years we get a few feet of snow, and this year is feeling a bit that way..... My "booth" is heated, but loses temperature when the fan is running steady, but probably not below 60. I'm going to spray a bunch of miscellaneous components and the underside of the floor before shooting the chassis, so should get some idea of how quick the clear sets up. I may try the retarder on the clear only if it's giving me trouble.
 
Shine you mention "dusting" the clear on. Are you saying you don't want it to flow out with each coat or just to dust in on in light coats until it flows out? For those that don't know me, I'm obviously an amateur painter who gets great enjoyment from doing my own cars, but am short on experience.
 
Shoot it like lacquer . If you shoot it heavy and miss a place it's hard to come back . Build it wet by dusting light coats .
