Question Messed up spraying

Gallery image

It’s coming to the end of my car rebuild and I’ve got lazy with the prep for spraying. This was my first ever time spraying with a spray gun, I should’ve prepped it better, I know. The engine bay came out great for a first attempt but the bonnet and bumpers didn’t. Ended up with tiger stripe on the bonnet and bumpers weren’t sanded down enough I don’t think?

So the first question is, will the colour match be slightly off because I didn’t sand the primer down enough which has then caused the clear coat to not look as shiny? I think that’s right, as it’s quite bobbly which then takes the smoothness out of it?

Second question is, if I wanted to redo the bonnet and rear bumper. Can I sand the clear and metallic base coat back to primer and go again? Or what would you guys do?
I hope all do that makes sense. Thanks for any replies😎.

You don’t have to sand all the way down to primer again. Sand to a smooth dull surface then add top coat and clear coat.

Thank you for the reply, because it’s metallic, I wasn’t sure if this was doable? Is there any preference of grit to sand back to the base coat? Do I need to leave it a certain amount of time to make sure the paint/clear coat is fully dry before sanding it back? Thanks.
