I wanted to see how hard it would be to polyurethane a completed airframe for painting and how hard or easy it would be to slap on a simple paint job.
For any airframe that is geometrically more complex than the Nutball I'd recommend treating the parts before assembly and then painting.
In the video I demonstrate how I:
- Use the same basic technique for poly treating the dollar store foam as my other video
- Mask off a basic two color paint scheme
- Apply the paint and remove the masking
Some portions of the the video are sped up to save time but I wanted to be sure and show all of my steps.
In the end I had a treated swappable airframe that was water resistant with a pleasing paint job.
- 5 minutes to treat and wipe the top
- 5 minutes to treat and wipe the bottom
- 1 hour for the treatment to cure
- 10 minutes to mask off the painted areas
- 10 minutes of spray painting
If you don't count the hour cure time for the treatment I spent about 30 minutes total applying the treatment and painting. If you wanted you could create a much more complex paint scheme with some creative masking and custom designs. Having the poly on the foam core makes the masking tape come up easily without damage.
Minor update: Here is a FT Flyer that I treated prior to assembly and then painted with the same technique
