After I started painting and assembling my grain elevator I noticed these nasty mold marks(?) At least I think that is what they are. A few decades ago when I was putting together models of PBY’s, B-17’s and Junkers I seem to remember there was a putty that could be used to fill these and my less than perfect seams.
I was wondering if anyone has ever used lightweight spackeling compound for this of should I just hold my horses and wait until I can get to a hobby shop?
I haven’t ever used that on buildings myself, but if I remember correctly, I think I’ve seen someone mention that recently.
Another option is to take one of your throw away sprues, make shavings out of it, and combine some glue (I’d use testors tube glue if you have it, not sure how this would work with a CA). Mix up the sprue shavings and glue to form a paste. Just smooth it onto your building. Try not to use a lot of glue (add it little by little until you have a nice paste). You should be able to sand it down smooth once it’s completely dry.
I’ve only used that method on small things, but for that, it worked well. You might want to try this on a piece of scrap, or on a unscene spot. Just to get the hang of it.
Another perhaps cheaper choice may be body putty from your local parts store. Not Bondo but you can buy plain green putty in a tube. I’m sure it would work just fine, and save you some bucks at the same time.
