70elky396, There is a product called V.L.P. and it is made to repair these cracks. It's also made to fix dishwasher racks that are broken. the stuff really stands up to heat without cracking or breaking again. Second you will need a vinyl repair kit from Permatex. First of all let me tell everyone that getting a perfect vinyl repair is pretty hard but getting a 95%+ repair is possible. The thing we are trying to achieve here is to keep the crack from getting larger. It's kind of like getting a windshield repaired after a rock has put a bulls eye or star break in it. Anyway V.L.P. is a clear liquid compound which makes it so you don't have to recolor the area if you don't want to but I recommend doing so if you can, or using the color compounds from the vinyl repair kit. First on a hair line crack where the vinyl is not lifting or curling simply put the VLP on a plastic razor blade or spatula and use it sparingly you can add more later if needed and fill the crack until it is level with the surface.Then from the vinyl repair kit find a piece of graining paper to match you dash and then put down just a little more of the VLP on the crack but this time use a toothpick or a needle, the object here is to just trace the crack with the VLP while laying down just enough of the product to make the graining paper do its' thing. the key here is not using to much of the compound and having patience. Take your time. Tape the graining paper down and leave it for 1 hour. Don't pull the paper off any sooner or you will probably have to do the repair again and the second time it will really show for sure. The Permatex kit also has a filler but it doesn't seem to work as well as the VLP. The vinyl kit has color comounds you can use as well with the VLP to help with the repair just follow the instructions that come with the kit. If you can find an old door panel or something to practice on before you do the repair on your dash it will help you get the hang of what I'm trying to teach here, it's better to make a few mistakes on a piece that you don't care about than one you do! I hope this helps and if you have any questions let me know, Dave. NOTE: If you are using the VLP only to do the repair you do not heat it up with the iron from the permatex kit. Only use the iron from the permatex kit if you are going to use the color compounds, that's how you cure them. Also I got the V.L.P. from an upholstry shop here in Washington called Sure-fit and I don't know if they are a nationwide chain or not. I know they are pretty big though. The permatex kit came from my local auto parts store.
