So basically I am selling a 2018 Camry to carvana today and they require the license plate to be removed. Last night I tried removing it and both steel screws are rusted tight. One screw the Philips head is starting to strip and the other screw turns 1/32 left and right but it feels more like the head it going to twist off the shaft. I sprayed them with pb blaster last night and have not done anything yet. I think my next step will be to use my impact screwdriver. What other tips do you have. The screws have been on since the car was new. Thanks
