I put the Soudal range of gap fillers (caulk) to the test against the OG Polyfilla. Gapping such a huge part of my process, and it's taken years to track down a system that works and performs the way I need it to. Give this video a good watch to see how different gaps perform with flexibility, elasticity, and why this is so important in any repaint. I worked with the legends from  @GOIndustrial  to put this test together. Jump on their online store to grab a few tubes to test for yourself!
