T Molding Help!

Hello I am a new teardrop builder and brand new to the forum. I have almost finished my teardrop and im to the doors and I am having a lot of issues. I originally bought 1" aluminum T bar and it was incredibly strong and I had no chance of bending it around my doors. Licking my wounds I ordered thinner T-Bar from McMaster Car http://www.mcmaster.com/#1668t72/=sv4yvy. Again still too stiff to bend. Still tried to bend it (much heat applied) and of course it kinked. I used both previous options to save money on shipping and keep it cheaper than shipping it from a teardrop part supplier. Well now I have spent about the same as if I would have just ordered through a teardrop part supplier. I am wondering about where people have bought their T molding, I have heard carpet suppliers may have it? I haven't put my build into a better online album but here is my build on facebook. I appreciate the help!
