Hi Friends,
Please see if i am right about my belief.
A lot of discussion on the internet about how clear coat effectively blocks UV lights and protect paints.
But with solid, colors, i do not like clear coats. Just i do not see any advantage using them. And they have extra difficulty in paint matching.
By the time, with clear coat or single finish you still will have fading problem. Either clear coat will get scratched so it will fade, or the paint without clear coat will fade.
Both can be fixed by sandpapering and polishing. If basecoat under clearcoat fades, there is no way of fixing it without repainting it.
But i have seen another disadvantages with the clear coats, was that, most of the time you have to repaint the entire panel. Otherwise overlapping areas would be noticable.
Because you have to sandpaper nearby areas of the repaired panel, And clear coat cant hides sandpaper marks easily. So even if you cant see the sandpaper marks under clear coat, still micro scratches will change the color under the clear coat.
Single stage paints are more forgiving in this term. Just partial paint, then sandpapering and polishing result in great paint match
With glossy finish, there should be no visual difference between single stage and two stage paints.
But i think, by the time, once micro scratches accumulated on the paint, making finish look slightly matte, two stage paints behaves worse than single stage.
Because ones clear coat becomes matte due to micro scratches, and we see is more frozen grayish color of the clear coat than the pigment under it(Especially if clear coat is thicker).
Please correct me if i am wrong. i am planning to repaint my black car. So need suggestions
