First thing, how much where the stripes and what did they charge for the install?
For future reference:
For this kind of work or any work on your car, I would have done one of three things:
1. I would have the shop order the product you want and install it. If they won’t order a specific brand, ask what will they order and will it be sufficient for you? I would have them tell me specifically what I can expect from them as a finished product (I would make sure I had it in writing). This will limit your liability as a consumer. Always pay for parts, work and services with a credit card (This helps in the dispute process if there is a problem)! I would want to know if they have done this type of work before and if they have, do they have any pictures of the work (pictures would be for appearance work). If they can’t or won’t do that, find a different shop.
2. Buy the product yourself (like you did) and have the shop verify that they can install it properly. Always review the installation procedure from the manufacture so you know what to expect from that particular product. Inventory what you get and verify what your expectations are with the shop installing the product. Get them to tell you what liability they will take before the work starts! Get it in writing! Make sure that it is clear that if there is a problem to let you know ASAP. Again, as in #1, pay with a credit card and ask if they have done it before (always verify or get them to guarantee 100% satisfaction).
3. Buy the product yourself (like you did) and install it yourself. Here you take the liability but you have the peace of mind that any screw up is yours. In this case, it is difficult to get a refund for a defective product (e.g. stripes, electronics, ect.).
As always protect yourself, get it in writing and pay with a credit card. If you have a problem, don’t wait to dispute the charges (never wait more than 2 weeks). Don’t let them string it out. Remember, you truly get what you pay for!
In this case, they should redo the work right or restore the car back to the condition it was in when you brought it in (they should also replace your strip kit).
Good luck and keep us up to date.
