Reforming the dome over a speaker cone?
Any car panel-beaters on board.
You know thew ones. A large angular dent in a car body panel and you hand over some cash and they say turn round a second/ walk round the block. Then they kick the panel, but they know exactly which spot to kick. Working speaker but the large perforation-type front grill kicked in or dropped so it touched the cosmetic dome at the centre of the cone leaving a number of depressions. I tried heating with a hot air gun to maybe soften and sucking with a vacuum cleaner hose - no good. Tried some dabs of hot-melt in the dents, alowing to cool and pulling in conjunction with 1 pound weight in some undeformed areas re-created the dome and then lightly heated with hot air to remove the glue - but didn't cleanly release and had to dust with toner powder to matt it out - but otherwise a re-formed dome. Anyone been here before with better ideas. ?
