Onto my next vintage build, the Centuri Space Shuttle, right out of the bag. This kit is pretty old and the balsa is typical die crushed, but this time it is also light weight. I was able to remove all the pieces and sand smooth ready for filler. I won't be around the house much I am thinking about filling the balsa with FNF. This would be the first time I tried FNF on a vintage build so I wanted to practice first. I used some spare balsa and cut out a set of large fins and smaller fins to practice on. I put on the first coat of FNF and man did everything warp, but when it dried everything was nice and flat, go figure. I sanded my practice pieces smooth but looks like there are some spots that need touch up. So I have a couple of questions......When applying the touch up areas do I use the same thick mixture or do I use a thinner mixture of FNF? Also the edges were a bit challenging to sand after applying the FNF. The FNF goes on thick hiding the front and rear sanded edges that were sanded to shape, next time I will apply a thinner coat. I will see how these practice pieces go then decide if I am going with FNF for this build, or just wait till I get home and use Brodak sealer.
