Walked into a shop in Portland that still uses a guide coat for every single job

Saw a guy in SE Portland this morning spraying a 2015 F-150 and he had guide coat on before he even touched the gun. Told me he does it every time because "it saves me one repaint a month minimum." Has anyone else found that a quick dusting of guide coat really cuts down on rework or is that just overkill?

I've been doing bodywork for about 25 years now and I tell younger guys all the time that guide coat is not some old timer habit that's a waste of time. That guy in Portland is right about saving repaints. A quick dusting of guide coat catches the low spots and sand scratches you'd never see under shop lights. It's especially good on metallic paints where the flake hides imperfections until clear goes on. For the 30 seconds it takes to spray it on, the payoff is huge when you're not fighting orange peel or fish eyes later. I'd say it's the cheapest insurance you can buy for a paint job that's gonna look right the first time.

Bring up something else that nobody really talks about with guide coat too. It's not just about finding low spots, it's about teaching your fingertips what smooth feels like. When you're first learning bodywork, your hands don't know the difference between a 180 grit scratch and a finished surface. A thin layer of guide coat forces you to really pay attention to the feel of the sandpaper as it cuts through. That feedback loop of seeing the dust come off and feeling the transition is how you develop the touch to block out a panel blindfolded later on. Without that visual aid, a lot of guys spend years not actually understanding what their hands are telling them. It's like training wheels for your sense of touch.
