Did a similar treatment to my 1991 XLT last summer, it came out great and am very happy with it. Main reason for oding it was to prevent the rockers from rusting out which is a common problem for the X. Will post pics when I get a chance. I will say that I did have to touch it up a bit this summer where is had chipped, mainly around the doors where it gets the most wear. This job took me two full days ( I am very particular, prepping the surface and masking it off took all the time, painting on the liner was a breeze, I used two coats of liner...for the cold days) in slightly rainy conditions and working outside, could be done in a full day if temperatures are right and using a well lit, spacious garage.
