Vent: A painter told me my prep work looked like a 'rust farm'
I was getting ready to spray a quarter panel on a 2015 Silverado, and the painter from the booth next door walked over. He pointed at my feathering and said, 'You're leaving too much old primer, that's a rust farm in a year.' I was mad at first, but he showed me how he uses a guide coat over the whole area to find every low spot. Now I always do a full guide coat, even on small jobs. Anyone else have a trick that seemed like extra work but saved you in the long run?

Shortcuts always cost more later.

Oh man, that guide coat trick is one of those things you never go back from once you try it. @seth_wells49 is dead right about shortcuts - I've seen dudes skip it to save 10 minutes and end up re-doing a whole panel months later. It's wild how something so simple catches all the stuff you'd miss with just your eyes.

I read an article in a body shop trade magazine a few years back that called guide coats the cheapest insurance policy in the shop. It stuck with me. That painter did you a real favor by showing you, even if it stung a bit at first. Skipping that step just leaves hidden problems under the paint. I've seen jobs come back with blisters because someone got in a hurry and trusted their eyes alone. Now I won't touch a block without a dusting of guide coat first.
