But then a completely non-binding. But reader Hans w. te R. took the trouble to inform us that he sprayed his classic with 20 spray cans from the Action. Such a spray can costs a euro or two ...
Well, we have recently seen some matte black rolled young timers. So maybe spray cans are not that bad. Without an evil word about the idea, the implementation or the product: You can assume that the mechanical properties of the paint from such a bins are considerably less than that of a real car paint ...
So just keep saving.
For rat look or other matte colors, such as army green or old-fashioned gray, this will work fine. Also, a thousand times prefer to see a car that is good in somewhat cheaper paint than 1 with 4 different colors of sheet metal and visible filler spots.
By the way, the paint quality before 1950 was still far from what it is today, so especially on pre-war classics I do not rule out that even cheap modern paint is technically better than the original paint at the time.
