I got a little heavy spraying awlgrip on a drive this morning and have a pretty bad sag on the side of one drive.
I've never used this stuff before, can I sand it out and buff it or do I need to sand the whole thing and shoot it again?

your probably better off to sand and re shoot. The UV inhibitors are at the surface and I dont believe its good to work the surface of Awlgrip

Yeah, that's what I've always heard, but was hoping for a quick fix.
This stuff not that easy to spray and not very forgiving.

You can sand it and pokish it but you should wait a week or two so it cures completely or the run you sand out will actually invert when dries completely. Your best bet is too reshoot and watch your flash times with a cooking timer . If its 15 min flash go 20. Dont heavy coat it . If you think first coat is a little dry get it on second as it will all blend together in the end.

glassdave is right.
If you mess with Awlgrip like buffing or sanding once it's fired off thinking you can rectify a problem you've fuxxed it .
I can't tell you how many times I've seen supposedly 'trained' Awlgrip sprayers buff out an imperfection or attempt a blow in on the regular Awlgrip . ( Not to be confused with the Awlcraft 2000 which IS 'repairable' .)

Awlgrip will tell you that they know people that do it all the time but they do not endorse it and they will explain why it doesn't work because of how the paint lays down and cures.
