Spray painting and issues!

[KeZzZu]

Ok fellows, im atm modding my case and allready ripped whole case in aparts and started painting with white color... (not shiny white) issue is...
when i leaved old case color for background, sanded it ofcourse with 60/150/400 grids and painted it 4 times with very thin lamel... issue is...
when something sharp hits on it color is gone.. you dont need even heavy objective to do so even pencil can scratch it! so does the last lamel: dunno its name butt you will finish with it! does it make situation any better ? will it elast littlebit more againts scrathes? or shall i start again it?

ps: or should i just buy air prushing stuff?

got clear coat?

maybe u should've gotten a layer of primer before enamel .. but then again .. with primer, u dun have to use enamel ..

primer coat (1-2 layer) --> color coat (1-2 layer) --> clear coat (3-4 times thicker than color coat)

for futher inquiry .. u should refer to automobile spraying guide .. custom bikes etc ..

clear coat should be hard and somewhat resilient.

also good drying helps.

Maybe do a bunch of layers, not just one (in the neighborhood of 4+). Also, a clear coat would help a bunch.
