I have a small chip in the underside of my EPS sup. It looks like just the outer skin has chipped and the inner coat has not been breached. What should I use to repair??

I have used Ocean and Earth EPOXY Solarcure to preventatively patch tiny chips on the old Surfboard Warehouse brand sup.
Probably same stuff as Solarez EPOXY in the blue tube.

Works well so far.

Just use a super tiny amount and cover with glad wrap, make sure smoothed out nicely and put in sun for ten minutes or until hard.

Same here, just using Solarez that I spread into an ultra thin layer (basically a varnish) with a business card, and tape over it with some clear PVC tape. Don't forget to sand lightly all the parts that the solarez will be in contact with, for a better hold.

A convenient trick is to have an UV lamp to be able to perform the repair in any weather or time of day, or moving the board outside.
However, the UV-curing resins only react to precise light wavelength, so you must get an UV flashlight of exactly the wavelength needed for the specific resin... which is not the same for each brand:

For Solarez, it is 385nm (hard to find, most UV lamps are 365nm or 395nm), cf www.solarez.com/information-on-solarez-uv-flashlights/ A cheap one is the Trotec UV-Torchlight 5F uk.trotec.com/products-services/measuring-devices/leak-detection/hand-held-uv-a-lamps/uv-torchlight-5f/

For PhixDoctor ("Dura-Rezn") it is 395nm (I asked them). Note that PhixDoctor is an interesting alternative to Solarez as it has a nearly infinite shelf life, is non toxic, cures with easy to find lamps, and creates less heat when curing than Solarez (whose dedicated lamp pulses in order to avoid overheating)

Or you can put it in the sun.

Sun is not always there when you have time / are in the mood to do repairs...

Not having to move around the board to put it in the sun is a big plus too... I dinged boards while trying to put them in the sun :-)
