But FOLLOW THE TECH SHEET! Many bases have warnings IN BOLD PRINT do NOT sand the base! It will clearly say things like "nib" it or "Scuff" it which is NOT "sanding" it flat, that is two totally different things.

Read the tech sheets!

Our painter knows this. He just waits til he can sand it. Just like they were saying about ecoats... just clean and paint...yeah right! That crap didn't work and that was straight from the tech sheets.

You will have to re-base after you scuff it, Depending on which paint product you use as to how long you have before you can recoat or clear, As a 30+ year painter you can and will have adhesion problems if left to long before you recoat or clear, better to be safe than sorry especially with the time and expense of redoing it

It's wrong, I know guys who have painted wrong for 40 years and "gotten away" with all kinds of crap.

Following the tech sheet is the best way to get something done properly. And for a newbe it is of the UPMOST importance because they don't have the experience to wing it.

You have seem the thread on sanding the base right Henry? Interesting test on sanding base coat paint (against the data sheets recommendation)

You can skip from about the third page all the way to the last couple as the middle is largely a peeing match.

well I guess they're painting it wrong all the way to the podium with 1st place trophies. I'm sure there's a good reason why they do what they do but you're the expert here, or at least on-line anyways.

Henry, just what is so frightening about me saying to follow the tech sheet? There are different paints that you can sand the base, some you can't, some have a 24 hour window others have a 7 day window, what in the world is so wrong for me to tell people to follow the tech sheets?

I could be wrong. I'm not right next to them when they do this and most painters I know do follow the tech sheet but I have noticed a lot of them are more secure about sanding as opposed to scuffing. You don't hear anything about denibbing a sealer with say 800 and a little grease and wax remover but it's being done. These painters I speak of are the best of the best in this area and have proven it with their work. Theory of application is important though so don't get me wrong.
