The local museum aquired a building they are fixing up. Someone alredy painted a panel over the door for a sign. Untill I check it out, I am going to assume that they used latex paint. Since I will be putting vinyl lettering on it, I'm wondering if Ronan block out white and then One Shot would work over latex or would I be better off priming over their paint with a universal latex primer like Jay Cookes and then One Shot? Or can One Shot go right over their latex if I scuff first?

I'm always afraid of repaints, because even if you reprime it, your primer may be laying on top of an ill-prepared job.
I generally will cut a piece of Aluminum, or DiBond to size, and drop it in/over the existing face. (this works especially well if that existing face is, (and if this is an old building, chances are it is), lying within a "transom window, or frame.
I feel I have more control over the job if I'm starting with a fresh substrate.

1-Shot will work fine over the existing paint, be it latex or enamel. Be sure the existing paint is not lifting or peeling, and let the customer know that your lettering can only hold up as well as the paint beneath it.
If this is on a glass transom, I would use Rapid Tac to remove the application tape from vinyl, as a safeguard against pulling latex from glass.

Nothing's a surer bet than starting with a new face.
And the cost of a new face, versus the labor, materials and the RISK of scraping, priming and backround painting is...well, there's no comparison.

I have painted over previously painted latex (in good smooth condition about a yr old) with one shot with no problems, however I don't sleep well when I do things like that so I will only work on a new substrate in this stage of my life....so I would jump on the bandwagon with Brian and Danny on this one just for the sake of saving yourself from having to do it again and possibly on your own dime if the paperwork wasnt written in your favor...do it right, so you only have to do it once. CHEERS

Hi there Dave. Another possible situation that can bring you some real grief is this: Some Exterior Latex paints are also made with a soil/stain resistant feature. These tend to cure with a waxy feel to the top surface, and they do shed dirt ( it won't stick ). The problem is that paint or vinyl ALSO won't stick to this type of paint. Trying to apply 1-Shot will be like trying to paint on wax paper, and your vinyl will lose adhesion in only a few days. Make sure that whoever painted that panel, didn't use that type of paint.
