Steve we also just stripped the paint off the drip cap and it did work as we saw the video on VTS.
We used a small hand held Benzomatic torch TS4000 and laid the drip cap on some rocked landscape area.
We just patiently kept heating it and watched it change colors then heated it a bit more.
We didn't pick it up, as we didn't want to distort the shape of it, until it cooled off. We green pad scrubbed it till the white ash came off. Our green pad was not the soft bumpy kind with a sponge attached to it for dishes. We used a mote aggressive thin green pad that you might use more in a more abrasive manner.
