Lowering under hood temperatures is always a positive thing. One way to help lower those temperatures is to coat your headers with a coating that will keep heat in its place – out through the exhaust. Tech Line coatings are a DIY that you can use on almost anything you can shoot with a paint gun. You will need a source for baking certain coatings, but please don’t use the one in your kitchen! The coatings that do not require baking can be installed in a few hours. They are sold in 6-ounce containers that will allow you to coat a set of headers and even some of your piping, if you apply the coating right.

Tech Line has many different coating options to match the coating with your paint theme.
If you are reading this post and wondering how you can do more than just coat your own headers, you are in luck. Tech Line has developed a program with Texas A&M that gives someone the chance to become a trained applicator of Tech Line’s performance coatings. The partnership is offered in your choice of six different, three-day training courses. You will learn everything from product selection to mixing and preparation before coating. The best part is that you never have to leave your shop to complete the course; samples are sent to you and then after you complete the coating work, simply send them back to be reviewed and tested for quality. If you pass, then your certification is good for two years.
