not hard to do , use at least a 1/8" thick flexible pvc sheet which u can get a piece by any sign making shop , cut out shape & secure it to sheet metal with self tapping screws [rivet nut & bolts wud be d better way if u have d tool to do it] , if its a odd uneven surface shape that wont sealed with flat pvc sheet then u will have to make it contoured with fibreglass & resin
then u simple sound mat over this patch panel & surrounding areas too ... i sure u can find videos of this on youtube
