I can't take my car because my sister can't drive a manual and she feels unsafe in case of an emergency, so we're going to be using my sister's 2001 Saturn LS1 and figured I would do some temporary aeromods.
Would it be ok to make grill block and attach it with masking tape? I don't want to mess up the paint on the car and wasn't sure what would happen to the tape when it baked in the sun and potentially got wet in the rain.
Any other ideas? All mods have to be taped on because I don't have permission to drill holes in the car.
