Howdy, first time poster here.
I'm in the middle of repainting the hood on my '69 GTO (long story, had an engine fire years ago that bubbled the paint and just now getting around to redoing it).
I painted the whole car myself about 10 years ago and it turned out really well, considering that it was my first ever paint job and I chose black (duh). I used all SPI materials then too.
Anyway, back to the current question: I got the damage repaired, blocked nice and flat, sanded it to 600, sealed with SPI Epoxy reduced 25%. It looked "mostly good" except for a couple places where I got the sealer on too heavy/moved to slow and got some orange peel. I let it sit over night (actually a couple days), and sanded those spots out with 600. It looked good to me, but when I started applying color I started to see some fine sanding scratches showing up that either I just missed or just couldn't see in the sealer (I'm 67). They were still visible after 3 coats of color so I decided it was time to stop, drop back and deal with them before going any farther and digging myself any deeper.
My current plan, unless someone can tell me this is a bad idea, is to go over the whole thing again with 600, then 1000, then go back to applying base coat. Sound ok?
Another alternative I guess would be to apply another coat of sealer and not sand it this time, instead start shooting base after the 6 hours recommended in 'perfect paint job'. I'm not sure if it's "ok" to shoot sealer over whatever base is left after I sand it. So that's another question I have.
I'd also like to know if there are any tricks I can use to see and make sure I've got all those tiny scratches out before I start spraying base again. They're really hard to see until I get color on it, and then of course it's too late.
Thanks in advance,
Bear
