1961 PV544 Project - Update 7
As I said in the previous article:
"Given what I had found while stripping the interior floors and the trunk, it made sense to do the same to the underside although I think I may have naively thought I might not have had to do this when I got the car after having given it the once-over at the previous owner's garage."
Needless to say, stripping the underside while lying on a concrete floor (and during winter) does not compare favourably to stripping interior floors and trunk areas.
Unlike the interior surfaces, the bottom had been treated over the years to a number of coverup solutions that made removal even more difficult and messy.
I found: factory primer/paint, additional primer layers, additional paint, factory undercoating in some areas, other spray-on undercoating, manually applied undercoating and more of the dreaded "rubberized mastic coating" first encountered in Update 3. This stuff was truly unbelieveable. As I said earlier: "...was almost impossible to remove. Heat didn't help as it turned the stuff to goo which meant cleaning the knife constantly and the fumes were ugly. The best method turned out to be sharpening the putty knife to a razor-like edge then working it under the material."
