Up until now, the only work that had been done to Caboose was stripping the interior and removing as many non-essentials as possible. In the process of doing that, we came across a fairly serious problem – MAJOR corrosion damage in the form of two large holes in the rear strut towers.
It was obvious to Naresh and I when we bought the car that there would be some issues with rust based on the condition of the exterior of the car but we didn’t expect it to be this bad.
Slightly discouraged, I went back to work the next day and started talking to some of the car guys about the situation and what the best way to proceed would be. Luckily enough, a very generous co-worker offered me his MIG welder for the weekend and said “Have at it!”
And so I did :)
Now I feel that I should put a disclaimer before this next bit – my welding experience is limited to a 3 hour welding lab that I took two years ago while finishing my undergrad. Needless to say, the welds you are about to see are pretty atrocious. That being said, they are better than giant holes :P
So a couple of weeks before Christmas I went out to Shawn’s to work on the car. My friend Bobby, who couldn’t turn down the opportunity to play with a welder, also made the trip up from Montreal to help.
With a borrowed MIG welder (running flux-core) and two 2′x4′ sheets of 22 awg cold-rolled steel (sheet metal) we went to work.
We started by grinding the area around the two holes to smooth out the jagged edges and find some clean metal.
After taking some rough measurements, we cut out our would-be patch and set about welding it in place. Before sending me off on my way, my co-worker had given me a helpful tip about welding patches. He suggested drilling holes around the perimeter of the patch and filling them in to make a “home made spot weld.” I must say, it was a great suggestion.
Having drilled one hole roughly every 2″ around the first patch, I sat down in the trunk of the Nissan to start welding. On my first spot, I blew a hole right through the interior body work. A quick adjustment of the current and a quick tweak of the feed rate and I was back to work.
Filling in the drilled holes worked very well. Unfortunately, tacking and sealing the edges of the patches didn’t work out as well.
The metal was too thin and would just melt away when we tried to weld around the perimeter. To compensate for this, we drilled more holes in the second patch. This worked out very well.
All in all it was an amazing experience. I learned a number of things, one of them being that I can’t weld to save my life, and the other that welding is A LOT harder than it looks.
While the welds certainly aren’t perfect, they’ve already passed their first test in the form of our first Winter Snowcross.

Surprisingly, everything went great! Phil, Chris and myself were able to stip the interior COMPLETELY out of the Festiva in about 45min :). It definitely helped that we didn’t care about breaking anything. We started by removing the back seat, and then continued to remove the carpeting, all interior panelling/plastic, glove box, trim, door panels, headliner, speaker wiring, and the rear wiper and wiper motor. We finished by taking off the catback muffler since the catalytic converters weren’t there anyways!
