Hello together, With my crafter there are a few battle tracks in the hold. Besides there are a few holes through rivets, with which e.g. several airline rails were attached to the walls (the rivets I removed, but there are of course the open edges and ridges. Before I start to expand the crafter (ground plate, insulation etc), I wanted to seal these blesurs so that condensation and moisture have no easy play. It is expressly not about kosmet It’s all about rust prevention. How would you treat the bodies? Does it matter whether the bodies will survive later? Note: The vehicle should be preserved later on. Have already been in contact with a specialist company. Only as a comment, if the topic comes up…
