Glue, Tape or ? to attach a light weight solar panel?
I am going to install a 100 watt Renogy flexible solar panel to the top of my 2350 Phoenix Cruiser. It will supplement the existing 100 watt regular Renogy panel I installed earlier this year. The 100 watt does an OK job keeping the batteries charged when boondocking, but I need just "a wee bit more" power as Scottie used to say on Startrek.
This panel only weighs about four pounds and is 42" by 21" by about an eighth of an inch thick. Here it is:

My question is this: what should I use to fasten this on the roof with?
On the first panel I installed, I made struts, used Z mounts, drilled into the roof and sealed all the mounting with Dicor. Since this one is light and flexible, it can be mounted directly flat on the roof and I don't know whether to use 3M tape, stick it down with DICOR or use some kind of exterior construction glue. Any comments or suggestions would be great. The diameter of the small grommets on the panel would only allow for using a screw of about 3/16" diameter if I drilled into the roof, which I would really like to avoid, so I would like just to stick it on there using something.
Thoughts?
