I fixed mine myself but I have prior collision repair experience, Problem with drilling a hole is, you have a hole when complete. Using proper 3M or similar kit you won't. I did mine by using Gorilla HD tape on outside to reinforce during the repairs then bonded inside using the chemicals supplied in the kit, but you need (or my kit required) a twin nozzle "caulk" gun to dispense the chemicals. Work time once dispensed was short and if you had never done it before you could have a messy looking repair. You also have to prep the inside of the crack correctly to get repair to bond and correct grinding, sanding disc's for finish work.
Just saying, body shop urethane repair guy that does it for a living, and has appropriate tools should be able to make it almost invisible from the inside ( and will be with a tourpak liner) and the outside will, or mine did, just have a slight almost invisible seam where the repair is. Average person would never know mine had been repaired, color of the unit will have some effect on visible "crack" when completed, a dark will let it go away, bright orange will show more.
Couple hours of body work time and the correct kit would be money well spent if you've never done it before.
