Replacement decals arrived yesterday and everything is now back on track.
Cheers guys.
Paul, firstly, thank you so much for the kind offer.
Secondly, I now have a decal sheet I can try that tip on...
And last but not least, the lumps and bumps were being pre-painted prior to being placed in position.
I`ve found that if I just painted the lumps/bumps, the bit of glue used can have a smear effect if you have fat fingers like me.
So I now paint and then gloss all these bits, then leave to dry, so it reduces any smear effect.
Will hopefully have this completed by the middle of next week.
