1. RECOVERING WITH VINYL Many upholstery shops are able to recover simple dash pads. The down side is sometimes they have to use seams in order to go around curves or angles. To hide the cracks from showing through a layer of foam must be glued on first before gluing the vinyl on. This may cause the item to look bulky. Also if the wrong vinyl is used, a fog from the vinyl can evaporate and coat the inside of the windshield. Don't give up on your local upholstery shop. Depending on the item, sometimes they can recover the item without the fog, bulkiness or seams but this is generally rare.
2. VACCUFORMING WITH VINYL The most expensive and longest wait. The main brand is Just Dashes, I believe there is another. The work I have seen is great,so close to original you could almost swear they made the item originally. If you don't mind spending $500-$1500 for a dash pad restoration & waiting up to 12 weeks for a close as possible looking to original this is the option for you.
3. VINYL REPAIR The lowest cost and shortest lasting option available. First we have to look at why the dash pad or door panel cracked. Expansion cracks happen because the dash pad expands with heat and you end up with a split because the dash vinyl has dried out over the years & will not stretch any more. These are the typical cracks you see in the direction of the front to rear of the car or truck. There are two methods.. A flexible or hard repair. The better of the two is the hard because that is one that looks the best. Negative is that if the dash or arm rest expands heat you will have another crack. The flexible one either get a valley when cools or pops a vein when warm. This method ONLY should be done if you a selling a car and just want a cheap quick fix.
4 AFTER MARKET REPLACEMENT Costs more than recovering with vinyl & repairs but less than Vaccuforming with vinyl. One big plus is there is no wait, you just buy it & install. The urathane ones will outlast anything maybe even you, for sure your vehicle. Mold lines that are viewed from the windshield in are common. Big negative because most are made with "molding urathane", it is very hard to color. Most paints especially solvent bases will not stick. There has been many complaints of dash pads not fitting. The urathane arm rests have not had the same fit problems just the coloring. Don't rule it out some do fit and you can get some in the right color.
