If these parts show on your model you will need to fix the clamp marks. If they don't show I would not bother with it as the crushing does not appear to actually break the wood causing weakness of the parts. Now this is how I would fix the parts and you can use this process for most any dents, cracks, gaps and repairs. The first thing you will need is some Red Devil Lightweight wall spackling you can pick it up at most hardware stores. Simply put a glob on the part use an old credit card and swipe the golb of spackle over the dents and let dry. Sand and repeat till smooth this stuff sands so easy and weighs very little plus you can fill some very large gaps with it and covering sticks to it good too. As you can see in my sample pics you can often get a good smooth covering the first swipe across the dents it will dry harder than the balsa but just as easy to sand. I use it for all my filling needs from pin holes to the usual dings, dents and gaps during construction. Try it you'll never be without it!
