I have a 1951 Chevy 3100. I took out the seat and did the floors with Por 15 put the seats and mats back in and the next day it started raining. The truck had not moved from it's spot. The next day there was about 6 or 7 water puddles about the size of a quarter on the floor? It was alittle wet by the clutch and emergency brake floor area probally the biggest area,a couple of drops between the wheel and the seat, a couple of quarter sized drops on the passenger side floor. There is a couple of paint wear marks on the dash above the clutch area is one and just to the right of the wiper control under the window. When I touch those spots they seem dry but I am thinking that water may run off them and then they air just drys them quickly. Any thoughts would be welcome as always. Thanks
