hey
saltydog...it sounds like you're building the same kit i am...the revell-monogram 1/48 p-40b tiger shark...and you are right, this thing's fit is just atrocious...anyway, i too have sanded away all the panel lines and rivets. Now I've re-scribed the panel lines using
blackwolf's awesome technique but I'm not going to replace the rivets since
greggers suggested, on one of my last planes, always sanding away the rivets because they ar the wrong scale for 1/48 and you shouldnt be able to see them at all...so I suggest not worrying about them. Good luck on the kit!
