Paint car parts with spray can or paint gun? what do I have to spend?

Hello dear Fornmembers! I bought a winter car for my girlfriend for limp €200,- without Tüv and it was necessary to make the cheap fit and to let it again nice assail. He was rust-free, for the new Tüv he needed new brake hose and new brake lines. New self-bended, good brake hose removed from the scrap yard and so the parts cost me only €30,- then to Tüv and now he has new Tüv 🙂 The Kleiine has climate, ZV, el. window and power steering, even 8 times over eift. year 2002 with 108000km! Now he gets new oil change with new air filter, new floor mats, then he is worth a few hundred euros more! Only cosmetic error, the clear varnish on the roof was shady and the bonnet in shiny black. So I bought 6 cans each with 400ml matt lacquer spray at the action market, with 3 cans of clear varnish, each can € 2.09 mega cheaply and pre-ground the whole with 240er sanding paper, then sanded with 800er wet sanding paper. Result Pfusch! Because it was better than before, but unfortunately shady surfaces, because with spray cans you can paint smaller surfaces, e.g. a fender perfectly, but large areas like roof, bonnet always cast shadows, because the can with propellant gas and the spray jet does not scatter far enough, so that always remains shadow formation. What do? For the first time I bought a professional gun set at Ebay for limp € 28,80 in a small suitcase. 1x a small gun with 0.8 nozzle for small things and a larger one with 0.13en nozzle and larger paint cup! 2* HVLP paint gun spray gun set pressure gauge cup case 1.3+0.8mm nozzles ( 253207886824 ) Then at the action market in Wiesbaden Megafunkten Streich-Acryllack 0.75 liter can for just under € 6,- water-based. So after home and 200ml mixed in paint cups with additional 100ml warm water and pure into the gun. Roof and hood sanded again with 800 wet sanding paper with hand. All well pasted off, in dry condition with silicone remover over it (the liter can cost just under 5,-€) everything wiped off, afterwards with sticky honey cloth again over it to remove dust particles. Today under my carport, side walls with blue foil 6×4 mtr. for €8,80 manufactured, the floor sifts, outside temperature 18° :-(then black matt tin varnish of the brand Spectrum 0.75 liter can acrylic paint for painting for 5,99€ bought at the action market. This color costs in the DIY market around € 20,-! Of which 200ml mixed with 100ml water and with the large quantity of water This was done within 10 minutes and the result, shadow-free, richly shiny surfaces, which are maturing when drying. The result is top! If I had had more time, the weather was running away, now it gets colder every day, I would have sprayed a filler before, to compensate for minor unevenness! But since the paint is matt, I am very happy with the result! Tomorrow I take a picture of the car and then you see the finished result! I found everywhere only those with 015 nozzles and the costs individually around the €28,- real cheap parts in the cardboard. Because I was lucky and met a car paintr there, who worked there and I showed him the set on Ebay with the HVLP technology he meant silently, buy the, which is very good and does its purpose! The HVLP-Tchnik consumes less air like the others and I get out with 3 bar pressure! My hardware compressor with max. 8 bar packed it loosely, He didn’t spit water either 🙂 But I’m going to buy a water separator for € 5,-? on Ebay, so that I always had the best result. If I had the roof and the bonnet painted with the friendly car painter, about 700-800,- Euros would have become due. So the whole paint shop cost me with gun, paint not yet €40,- and paint I still have left to spray the whole cart in black matte if I wanted! And I’m not going to tell you.
