With my new project, an early 60s ford, The dash top has the Vacuum formed plastic over a foam and steel core, It has the typical Vinyl cracking, a couple that are quite a big 5mm wide, these dash tops are rearer than the rocking horse excrement, so, It needs to be repaired, it will need filling and recovering with a suitable stretch vinyl, searching the new, elastic fillers for this seem to be few and far between, my thoughts are now heading towards Sikkaflex, as I intend to recover, the grain does not need to be replicated, so I am just using it as a elastic filler........ Your thought gentlemen please
