I am in the process of replacing all of the vinyl headliner on my 2005 Hunter 33. There is a track system. You will gently push up on a corner until the fabric comes loose. Gently pull the fabric out of the track. The fabric along the walls has 2 sections, a part that looks like piping, but is actually a 2 inch strip that is secured to the wall behind the track and folds forward over and into the track. The large center piece will tuck into the same track. If you are replacing the fabric at the edge along a wall, the part that looks like piping, each section of track must be removed to have the edge fabric removed. The valance is a piece of wood that has a track piece at the top The fabric goes into that track, wraps under the valance free edge and we ended up gluing it to the back side of the valance as we couldn’t remove it. We found the best instructional videos on tucking into track systems by googling Fabricmate on YouTube. These don’t cover how to do the edging but you will see how it works when you free the fabric. I also ordered the fabric tucking tools from them. In our experience, the very best way to get the fabric back in is with Star Brite marine formula white PTEF lubricant, spread along the groove of the track. The fabric and insertion tools are sprayed with Food Grade Silicone Spray. The teflon grease lubricant and the silicone spray make a huge difference when you‘re dealing with vinyl; they don’t stain the fabric either. Having the proper thin strong tucking tool is key, we like the tucking tool from Fabricmate as well as the rocker tool. I have loads of pictures if you need.
