Instructions for these are not included due to the fact that it is only recommended to have this installed by a professional. It is not recommended to DIY this install for safety reasons. As to the paint, that is just something from the manufacturer for better identification of products.

It’s been a year since my purchase and install and I couldn’t be more satisfied with Etrailer’s customer service and products. The door spring still works as good as it did when I installed it and I use it several times a day, five days a week. I have been so proud to recommend others that I know to purchase from Etrailer.
