Using bed liner paint to coat a truck is a way to get a bed liner without spending a lot of money. It trades some work for a lesser cost liner option. The funny thing is what it takes to put on liner paint is surprisingly little work unless you count what happens before you paint. If you have ever put paint on anything and watched what happens for some time, you know where the work is in a painting project. It’s always in the same part of the project. The real work is and always is in the surface preparation that must be done before you ever put a bit of paint on. Do the preparation properly and the paint stays on. Skip steps and you get trouble. That’s exactly the case with bed liner paint as well. It’s surface prep that’s the key. What it takes to get ready to paint is not really hard but it does take some effort, most noticeably in the cleaning that must be done.
