I was frustrated by some of the wide gaps between wings and fuselages on some of my models and was longing for an efficient way to fill them. Recently, I was sealing the windows on my house with caulk and thought it was too bad I couldn’t use this stuff on my models. Then I figured, why not? 

I put a small amount of caulk on a plastic card and gently filled in the seams of my Revell B-25J Mitchell with a toothpick, making sure the caulk filled them completely. I then wet my finger and ran it along the joint and presto! a really smooth finish. 

I recommend a quality caulk that is sandable and paintable. My results show there is no need for sanding if you get it right the first time. The good news is that if you make a mistake or don’t like it, caulk wipes up well when it is fresh. This method is probably best for straight line filling, but experiment. Depending on the size of the gap, there may be some shrinkage, so you may have to use a second application. My experience with this method shows it takes primer, acrylic, and enamel paints well.

Again, this is a quick, easy, and inexpensive method for filling in those pesky seams along the wings and stabilizers and getting a nice fillet.
