It doesn't matter what you're trying to do, there is a YouTube video to show you how to do it. Some YouTube videos are instructive in what mistakes NOT to make, but if you search around for a few minutes, you'll find a pretty good video to show you how to do what you're trying to do.
For example. Yesterday, PawPaw was driving his Mercury, and a young lady backed into me, with a Nissan SUV. It was a low-speed accident. She is okay, I'm okay, and after she apologized, she said "My Daddy is going to kill me." I doubt that, but we called the on-duty police and had a report done.
No real body damage on the sheet metal, but she crushed my header panel, the plastic/fiberglass/whatever thing that holds the headlights, grille and side marker lights. A quick Gooogle shows that it's about $100.00 for the new header panel and several hours work.
Did I mention that I love YouTube? I'm going to eave this right here where I can find it later. It closely matches the damage to my vehicle, and this guy shows me step-by-step how to fix it.
In another week or so, I'll order parts.
