Many thanks to all for encouraging words!
Before proceeding with this wip a welcome to Raul from Madrid.
Here some pics of rivets.
These are of the main chassis.
You can see the "dark side fo the moon": i didn't cut them since the body doesn't touch them:
Otherwise after glueing, I cut the rivet, sending them untill the rivet himself becames part of the piece.
For example, here the body part which covers the engine, these resin rivets were all sanded inside to allow the attachment of the white metal part under it:
Hoping to well answered to your question.
