Last time I had used two Vise-Grips to mate the engine nacelles with the wings. 

The upper parts of both nacelles didn’t mate perfectly with the top and the bottom wings. I had tried glueing the bottom parts first, but it did not work out.

So I had to unglue everything and then I used super glue at the wing roots. It did not work well either…

So Mother Invention had told me to…

Use a Vise-Grip…!

Well it worked a little but there were still visible gaps. I did not want to use a filler and have to file around the nacelles. Mother of invention told me to use a little dab of clear acrylic paint and take the excess of with my finger.

I always listen to Mother of invention.
