New to the water side of modelling and I decided to start with a Revell 1/144 Gepard-Klasse (143A) Schnellboot. This thing has been a pain from the beginning with poor fit and lots of gaps to fill. I have a couple questions as well. The first one being: How do you remove bondo or putty from unwanted areas?
The second question refers to one of the pictures below which is a closeup of what looks to be some kind of drain port, would these be more accurate if I drilled them out to be hollow?
Thanks for the help and hopefully I do this kit some justice in the end!
