Showerthought: Everyone says to always use a guide coat for filler, but I think it can hide more than it shows.

I was working on a quarter panel for a 2015 Civic and the guide coat made the surface look perfect, but after primer it showed a low spot the guide coat completely missed. I think we rely on it too much and skip the final hand check. Has anyone else found a low spot that guide coat didn't catch?

Guide coat is just a tool, you still gotta know how to use it right. A low spot means the light wasn't hitting it right when you blocked it, not that the guide coat failed.

Isn't that just how it goes with EVERY tool? People blame the thing instead of their own skill. Saw it all the time when I worked in a shop.

Okay but "blame the thing instead of their own skill"? Isn't that a bit harsh? It's just filler work, not brain surgery. Sometimes a guide coat misses a spot and you find it later, it's really not that deep.
