Well, my experiance with this is that I brought it in to get the brake recall and dashboard recall. My warpage is across the whole dash along the windshield, but it is only 'curled up' about 1/4 inch. I am getting a new dash because they said that they tried the fix kit, but it would not fix the warpage at the two ends of the dash... As to this 3 inch thing that everyone is talking about, is it 3 inches side to side, or 3 inches 'up' the windshield??? im only just curious, cause my dash is on order! hope my $.02 helps!
