Primer basecoat wo,dow

#1
New to the site. Have read a Lot of the threads regarding this question,but want to be sure on time from using epoxy primer used as sealer to time basecoat can be sprayed.
I sprayed the sealer yesterday with. Intention to spray the base afterward, but situation came up and I could not do so. Would like to spray base today. Would I need to wet sand sealer. It will have been 24 hours. All SPI products. Thanks.

The perfect paint job in the tech manuals says, after sealer, you can either lay base coat in 6 hours or another option is to wait until the next day, then wet sand with 400-800 grit and then shoot (pg 38). I just did this last weekend and it worked fine for me. It was only a test panel, but I put clear down and cut and buffed and haven't notice any problems (outside of the fact that I suck at cutting and buffing!).

Thanks for the response Chris. I saw that in the manual as well,but I've also seen alot of different answers on this forum.
I was hoping to save the wet sanding step if possible. Done enough sanding already if you know what I mean. I know there is more to come,just hoped to not have to do it this time.

I've been sanding for the last year...I'm ready to be done, so yes, I know what you mean. That amount of time is a game-changer for my planning, Barry. In a good way, so thanks!

Over the last 9 months i have been doing a lot of testing with different bases and learned a lot, your going to see some rules being modified in next tech manual and in the advice I give out.

I'm just to cautious and a perfect example is waterborne base, I have very-tight rules for clear being applied, I have gotten 100% adhesion two weeks later with no cleaning or sanding.
