BMS School Rocket, Build, Part 8, Paint & Mask

After a few white undercoats - The body was painted and overall gloss yellow.

A paper towel was rolled and slid into the front of the body tube to keep the paint out.

The four fins will be painted black.

I used my standard Scotch tape masks, the edges marked with an off brand permanent marker. I'd recommend using an actual wide point Sharpie to mark the tape, some of the off brand marker ink rubbed off on the fins and body.

Here's the rounded leading edge mask made up of a few small pieces of Scotch tape mask.

After the tape was pulled,

There was traces of black marker ink on the yellow body paint. This was cleaned off using a Magic Sponge. 

The Magic Sponge can dull the gloss, some polishing compound brought back the shine.
