bending aluminum angle to nice curves for trim

I've read all about annealing and bending the alum. angle for the trim and haven't been enthused about the process or results. Got an add from Harbor Freight (still 99% junk) but they had these things called stretchers and shrinkers that I had never heard of. Went down there and bought the displays ($200 for the pair that they come as) and went home and tried the shrinker (for bending flange in). I used 1" X 1" X 1/16 Al angle and was able to easily bend it to a 10 inch radius and could probably go much tighter. The results were PERFECT, smooth bends with NO kinks. The tool leaves some score marks on the surface of the Al. where it compresses it but these are easily removed with sandpaper returning to the original finish depending on how fine of sandpaper you use and how much time you want to spend. Another big plus (as I plan to use 1.5" X 1.5" X 1/16 (but cut down the vertical flange to 1.125" or a bit less) to form the edge of the galley hatch and overlap it on the side of the trailer for a good weather seal, is that the Al is not annealed (read weaker and easier to bend) and is probably work hardened a bit (read a bit stronger) so it will not be as easy to bend when it's cantalever out over the edge of the hatch. I can send pictures of the tool and the Al. I've practiced on to those interested.
