basically, it will take a few hours of prep work. depends on how fast you can tear down the interior, sand, vacuum, sand some more, vacuum, wipe with xylene, and then tape everything off. then come back and apply the liner. the application is super easy. it goes on very easily and quick. wait 1-4 hours before applying second coat. that goes on even faster. i suggest applying an additional 1-2 coats on the floorboard at your feet for the extra wear and tear. then you'll want to let it sit and completely dry at least overnight. if not more. just so it is not at all tacky. the beauty of herculiner is it bonds to itself, so you can go back later and apply more as needed/wanted. as long as you reseal the container, it will fine for future uses. we used a little less than half a gallon to do the interior of the S-10 above. you can run your wires under the doorsill trim.
