Estes Semi-Scale Saturn V, Kit #K-39, Part 28, Oops! I Screwed Up!

I usually have good results using the Scotch tape masks. Not this time!
The instructions said to "use a very fine brush" to paint the areas where the system tunnels are into the black areas. I decided to mask for the black areas.
 

Scotch tape was used for the borders of the black areas. The rest of the larger white areas were covered with brown tape and copy paper. 

I got paint bleeds at the tunnel ends. A glue fillet would have blocked the the paint. The off-white cardstock absorbed the black paint.
Bits of the cardstock wraps were torn off when the tape was lifted. I was careful - I removed some of the tape tackiness before sticking it on the model by pressing and removing it on my pantleg. 
I didn't apply glue fillets on the long system tunnels. The side  edges weren't smooth and the paint got underneath.

On the left you can see where the cardstock was lifted.
The mask in the right side picture came out okay. 

I'm not happy with the way it turned out. There's really no way to fix it unless I pulled off the old cardstock and tunnel details and tried again. I won't be doing that.
 
After the problems cutting the fin slots and this bad mask, this build is a "bust". 
Another glitch in a future post.

  1. Hrm... looks like painting the various bits and pieces -- before you glue them on -- would've been the way to go. Especially when paper wraps are involved. Clear-coating of the paper/cardstock might've reduced the chance of bleeding, but not the tearing when lifting the tape.

    1. Hi Anonymous,
      I did paint the tunnels, feed line fairings and ullage motors white before gluing them onto the model. I should have also pre-painted the black areas on the long tunnels. Oh well, live and learn.

    2. Hrm... perhaps using a Sharpie pen would've been safer? And oddly enough would've been sort of close to what the instructions called for.
