Quest Lil' Grunt Build #Q5014, Part 4, Grain Fill & White Undercoats

This is a show build for Quest, they requested basswood fins.

On the left is the 1/8" thick balsa that came with the Mean Green kit. On the right is the basswood copy for the display build.

There's not much grain in basswood but I still give it a coat of CWF and sanding. It also got a shot of filler/primer and more sanding.

The instructions don't mention it, I did round the leading edges of the fins.

Here's the fins glued on and fillets applied.

White undercoats followed.

I wrapped some 400 grit around a Q-tip for some round cushioned sanding (and no sharp bend sandpaper scratches) in the fillet area.

I didn't have any used 24mm engine casings to use on a painting wand dowel.

Use just over one full wrap of corrugated cardboard around an 18mm casing makes a better fit in the engine mount.

After sanding with some old 400 grit - 

I'm ready for a second shot of gloss white undercoat.
