Nope, just make sure that you flat it out enough or you will be able to see the difference between the layers. Other than that you will be fine

cool lol
if u sand it down bit too much, like to the primer or even to the plastic, would i need to reprime or.. ?

If the old paint is ok then just sand off the old lacqure and the paint it again. No need for primer.:thumbs:

its been lacquered and everything! Do I just sand down and prime it again or wot :P ?

All you need to do is just sand it down with 800's wet and then paint over the top. Just make sure the old paint isn't shiny anymore or the new paint will flake off after a bit.

just painted my interior, but now realised i want a complete different colour! Can I paint over the current colour, or will a need a new interior? or sand it down or something? can i do anything :( ?
thanks in advance
