What sealant to use here?

I have a rubber roof which I believe to be EPDM. I used dicor lap sealant to seal around all the protrusions (refrigerator, vent stack, antenna) and to seal between rubber roof and front and end caps. My question is where the rubber roof turns down to vertical surface what is the proper product to use between rubber roof and horizontal trim. I thought Proflex was it but just read on Proflex website:

Do not use on traffic-bearing surfaces. Do not use on extruded polystyrene insulation sheathing (Styrofoam, etc.), TPO, or EPDM. Do not use on acrylic skylight glazing surfaces. Do not use in areas where food is processed or stored. Do not use for potable water applications.

Attached is a photo of the area of concern. Also, do all the screws which attach the trim between rubber roof and fiberglass walls need sealing?

Dicor makes a sealant for use on vertical surfaces (Non sag they call it). Looks like a good place to use it.
To do the screws correctly I'd remove them, fill the hole with sealant, then put the screw back in.
Below are the part numbers for the non sag lap sealant:
551LSW 10.3 oz. tube White
551LSD 10.3 oz. tube Dove (Bright White)
551LST 10.3 oz. tube Tan New!
551LSG 10.3 oz. tube Grey New!

Well, I tried to get the chart right but the forum strips the spaces out
