FlisKits Tartar Build Part 13, Tight Sanding TIP

I wanted to sand close to the reinforcement pieces but folding a piece of sandpaper in half could cause scratches at sharp edge.

Another use for a Q-tip:
The cotton tip was dipped in water and the excess shaken off.

The round tip was flattened with my thumbnail.
Wrap some 400 grit sandpaper around the flat tip.
The cotton gives more support with less chance of scratching.

The inside edges of the reinforcement pieces are sanded.
