Smile straightening out the T-moulding

Hi, On our “new” 1980 Trillium 4500, we could not help but notice that much of the T-moulding that joins the seams had bunched up over time. I am told that happens from heat. Having seen a previous thread where someone straightened it out in hot water. I thought I would try it.

First I tried hot bath water, but it was not hot enough. So I got a big pot with a couple of inches of water in it, and brought it to near boiling on the stove, so I could see the bubbles and steam rising but it wasn’t quite boiling. That worked great. I immersed the moulding in the hot water for about two minutes, and it basically straightened itself out. I then plucked it out of the water and pulled it a bit so it was quite straight, then let it cool.

Putting the moulding back into the track was a bit tricky in spots, but mostly went well.

Below are some pictures of the before and after for a couple of the pieces. The wavy look in the roof "after" picture is waves in the ensolite left over after the moulding had been straightened. Hopefully it will fix itself over time.
