I have a 58 half ton chevrolet and had removed the headliner.Got rid of the usual surface rust and painted with the rusty metal primer.I was in the truck on a cold morning with heavy frost on the cab top. With the heater starting to warm things up a bit I noticed the cab ceiling was all wet. The ice had formed inside the cab also and now melted water was just hanging there.Does this happen under the headliner and inside the doors also? If so what can be done to stop this other than parking inside
