I saw a car the other day where the couplers on the cold air intake were glued on. Yes..GLUED! It looked like either elmers white glue or maybe even some type of caulk because it had seeped out between the tubing and couplers. There were no t-clamps or anything holding the couplers on.

 

It was a good 6 or 7 years ago, but in Daytona at a car show I saw an R33 where the owner had made his own bodykit out of bondo. In fact there were so many ripples in the trunk and hood it looked like the entire care was coated in it and hit by a hail storm.
