with the weather being as it is at moment, the only suggestion I can make is as follows.
You need a couple of buckets of boiling hot water and one of cold, plus some means of clamping the body.
Clamp the body to the position that you want, then heat up the water. Pour the hot water slowly over the shield, then cool it off with the cold water.
Or you can wait for a nice hot summers day, clamp the body and put out in the sun to cook.
After the body is very hot cool it off with cold water, then remove the clamp.
