This subject requires some "real" investigaion of the companies that "provide a warranty for their products"
Such as "who are they, really?"
"How long have they been in business of providing warranties/warrantied products, and are they just in a localized area or is the customer able to obtain warranty resolution all over the USA?"
"Does a through check of their business, show that they actually honor the warranty sold?"
"Is the warranty written in plain English(or whatever lanquage" that makes it very clear what is covered, for how long and what is the requirements of the vehicle warranty, what is the requirements of the "seller" and "application company" of the product/products?
Who administrates the warranty and any claims?
IT IS NOT THE DEALER WHO ADMINISTRATES OR PAYS THE CLAIM, IT IS THE COMPANY THAT SOLD THE PRODUCT AND "WARRANTY" TO THE DEALERSHIP. (this is where the detailer gets put on the "hook")
What is the exposure of the application company, are they legally liable for any claims?
Is it possible for the buyer to move to another area of the country and still be covered, to obtain resolution of a claim, should it be necessary? (in today's world, people move a lot, out of the area where they were when they bought products/warranty)
Should the application detailer be able to be reimbursed for any corrective work and does a check of the history of such show that they are?
A "big" thing in the "warranty" business is "who is the insurance carrier" for claims, or is the company "self insured".
This means that if "self insured", and they do NOT honor their warranties, IE pay as per the legal wording and coverage of the warranty, have not been in business for over 10 years, they will close up shop when the claims come in and leave the "detailer/dealership" holding the cost of making it right. ( research such company's as Thermo-Gard, Ultra Seal, etc)
Chose a company that has been in this sort of business for over 10 years, Google them. Sure, as with any insurance/claim situation, there will be some negatives, but look at the percentages, as often it is not that a reputable company does not pay a legitiment claim, but the customer is abusing the written warranty and it's requirements.
Most "real and long term" companies have written in the warranty, a time to respond, and as like the rest of the world, some will attempt to make claims that are beyond the requirements of the time allowed and the actual warranty as written. (your roof is 20 years old and now you notice it is wind damaged, etc)
There is "paper work" required, there are often, "not real world" sales claims made in the brochures, that have nothing to do with the "actual" warranty and what is required by the customers in order to maintain the vehicle and submission of any claims.
That is where the "rip-off" by such companies come into play and have given the whole thing a very bad name.
You got a Chrysler product, buy the Master Shield product offering, as it is covered and administered and paid by Chrysler, not some one who works from a UPS post office box.
You want to get in the business for other brands of cars? Find one that has been around for over 30 years or such and "READ THE WARRANTY(carefully and be able to understand it's limitations and requirements yourself before selling the products)--read THAT WHICH THE CUSTOMER RECEIVES AND HOW MUCH SMALL PRINT IS THERE THAT PUTS THE ACTUAL BURDEN OF CARE ON THE CUSTOMER"
