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. ? Weights and vacuum cleaner ?

Leaving it alone usually works well enough. Pressing the cone right back should ensure its up enough not to foul the pole piece. Doesnt look so hot at sale time, but as you say they can be difficult to get out.

I don't know why the vacuum cleaner does not work. It has always worked for me in the past. Maybe you need a stronger vacuum and a better seal to the dome.

I think it may have done , click noise , but I didn't think of getting some clear hose and flipped back immediately to previous state on removing hose. Next time I may try with clear tube and weights. Later I was thinking of a funnel of about right size for the whole dome , and connecting to vacuum
