Using these GrimmSpeed hood struts is a breeze. To open the hood, just lift it up a bit until you reach the neutral zone. From there, you can either leave it for a nice display or give a little flick to fully open it. When you're done and want to close the hood, hold it below the neutral zone and let go. It'll close smoothly on its own. As for maintenance, keep an eye on the power - coated finish. If you notice any signs of wear, it might be a good idea to touch it up to prevent corrosion. Also, check the struts regularly for any signs of damage or leaks. If you see anything wrong, it's best to replace them right away to keep your hood working properly.
