Since you live in Texas this will likely be easy! Wait another few weeks for it to warm up to 90+ and take some ice out of the freezer, hold the ice in you hand above the dent and let it drip onto the dent a few times and it should 'POP' out! If it does not work completely allow the metal to heat up again (maybe retry when the temp is actually warm such as 100+) and use dry ice (actually place a small, dime or less sized, piece on the center of each dent). Always be careful handling dry ice as you can easily get frost bite! Wear gloves! Have done this many times and MOST of the time it works well.
Good Luck,
