Thanks Cem .
I'm fortunate in having all that is required to paint . I have two compressors a 200 Lt 3hp and a small 50 lt to feed my air fed face mask. Three guns, two are gravity feed,  with 1.8 , 1.4 and 1.0 nozzles , The 1.8 nozzle is on a good De Vilbiss gravity gun which I use for primer filler coats , three sets of hoses, one dedicated for clean work, two moisture  filter systems . I use a final pressure gauge on the outlet of the filter block as I find the final gun pressure adjustment is done by "feel " depending on the gun used , paint and viscosity.
The car will be painted in clear over base the base being metallic and the clear 2K . I do like non scratch lacquer and have been using U-Pol recently on non car items .
The next items I have to buy are a good final polishing machine with pads as up till now I have done all finishing by hand that's why I was pleased to see your post on the 3M system.
Keep them coming .

good to see paint enthusiasts like me 

another improt experience I want to share is that, I made the mistake of buying the strongest and heaviest bosch gex 150 wrong .. its too heavy.. may be good on flat parts or wood  but on vertical parts its too heavy.. so if you are going to buy a da sander/polisher buy a small one which is very light (eg hitachi) .. normal orbital polishers are good but with on edrawback.. whatever finest grade polish you use they let path traces even if you overlap them with the softest head..  at first its not visible but after some washing and sun light they become visible.. so da sanders IMO is a must and must be used with soft heads very fine polishes for final polishing without secondary rotary action.. so they erase all traces left.. of course you can do by hand but it takes long time for a perfect job.. I also recommend hitachi rotary polishers.. be careful they need frequent oil changes.. I use mixture of thick grease  + ep 140 type oil in them..

and for scratch resistent laquer layer,  I have tried and tested several methods with it..  first problem is never laquer a complete car at once..

instead divide the job in  2- 3 portions.. because if you spray whole car laquer at a time , you need to start the next day without it drying properly or else you cant complete the sanding and polishing forever

so first application 4-5 layers (oroginal factory recommended is 2 but that with a factory spray gun robot which is different)  10 minutes between every layer .. next day sand a small portion with 600 or 800 wet if it sticks to the sand paper stop and wait a bit longer..  after sanding the surface to a smooth (ie without orange peel) wait another 1-2 days and then another 4-6 coats and then sand with 1500-2000 wet to remove orange peel again..  later 3000 and 6000 respectively..

in a paint cabin with proper heating this orange peel is minimized but still exists..  I never add reducer to this type of laquer so it gives better and clear shine..  after this final clear coat layer is very thick like a tank armor  can be hardly scratched but you can (not easily) remove it and it hardly burns under sun..
