Brad,
Whether you get paint protection from a dealer or detailer they are all pretty much the same. They usually offer 5 years warranty like I do but the warranty olnly covers the product.
If you do get it done and you read the fine print of the warranty it usually states that you have to clean the car with the specified car solution (which you have to purchase from them)at a minimum of every 2 weeks. Any tree sap, bird droppings, contaminants etc etc to be cleaned off straight away. You have to take it back for an inspection annually and if any panels are repaired or repainted then the whole car will need to be redone.
This basically makes it bullet proof for that there wont be any claims. If any of these things are voided then your warranty doesnt mean jack.
If you want your car to be protected and always looking good, you are best off investing money into some polish and a good sealant and applying it yourself every 3-6 months. This will guarantee maximum protection.
I would have mentioned this to you on the phone the other day but I was flying down the motorway

Sorry
Cheers
Dave
