DIY
The best thing for car headlights. I painted them in October and they still look like new. After sanding them with sandpaper, you paint them and have one less worry. You apply the first coat with a light stroke and wait 10-15 minutes between coats as the instructions say. With a second heavier coat, you get immediate results. 2-3 coats are enough. Personally, I did 4 coats (we can do as many as we want!). Each one slightly heavier than the previous one. I left it for half an hour on the third coat and applied a good fourth coat and that's it. Be careful not to overdo it and make it tear. You start with a quick stroke and slower towards the end. We let it dry for 12 hours for the hardener to do its job. And leave it for 24 hours for even better results. The more coats, the better. Of course, it will create the orange peel effect, like all paints even if you go to a professional. With a 1500 or 2000 grit sandpaper, you can remove the orange peel. Then you apply a fine cutting compound with a polisher and voila! There are detailed DIY videos on YouTube with the relevant product for anyone who struggles. And by the way, if there is any leftover, due to the fact that the hardener will mix with the varnish from the moment we open the valve, we store it in the refrigerator for up to two days. Otherwise, it can be frozen for up to four days. If we don't use it beyond that, it is useless and we throw it away because it will have hardened.
