Cheers, really appreciate all the help. I'll be honest, I was not expecting as good a result as I got. There is orange peel but only slightly I've had much worse when painting stuff before and was a scary thought doing it but the way I'm looking at it is.
Is it a professional body shop standard - No, probably not even close.
Does it look better than it did - Yes definitely all my spots from factory primer or the white undercoat that were showing through have gone the marks and scratches in the bumper after filling are gone and the result is better than expected.
Would I do it again - Definitely, considering I was quoted £600 for a bumper and bonnet at a body shop I'm managed to do the bumper for about £30 and a few hours work I have something that hopefully when polished unless really scrutinised will look great, it all ready looks very good just a bit dull.
