I was adding bb's to the engine nacelles on Star Trek's USS Reliant after forgetting to do so after gluing them together,
so I drilled a hole and inserted lots of bb's and lots and lots of
Testor's model cement and then sealed the hole with putty.
The next day when I check, the entire sides of both engines had
softened and distorted and was still soft. I had already spent countless hours on the hand painted Azteca saucer pattern,
so a fix was definately in order. After the plastic began to harden
after about a month it took a lot of putty, I got close to almost perfect and now it has just been sitting for more than a year.
The worst part is realizing (after watching the Khan flick several times) that I should have left well enough alone as it would have
been an absolutely perfect effect for battle damage.
The next bigger uh oh is a recent recreation of a decal on my ink jet printer. I had spent hours perfecting a 'Champion' frame decal for my newly powdercoated vintage bicycle, I mean the thing was perfect after reprinting it about 3 times it was flawless and the spray coat job for creating a waterslide decal was just right. I put high quality clear tape over the fully dried decal (still perfect at this point) carefully cut it out, soaked it and applied it to the bike frame. To make it more or less permanently attached, I thought I was trick using Mop and Glo
as a gluing agent. Went to bed very satisfied and woke up to find out the Mop and Glo had seeped through the back of the decal paper and blurred the sharp printed logo. Due to the clear tape layer on the front, it inhibited natural drying and the logo became more fuzzy each day. The final touch on an investment over 1,000 bucks! I am afraid to remove it and try again.
