My Linex liner was sprayed in 01, before hitch install. Is now faded but intact. My preference is to drill for hitch then spray, seal raw metal at mount holes.
Hopefully you don't remove much of the liner getting the bolts back thru the hole. I don't think it makes much difference holes drilled before or after.
I guess you could oversize the holes before the liner, but thats not such a great idea. I drilled mine after , and put a bit of silicone around the holes before tightening. no signs of rust or corrosion when the bed rails were removed. The puck system on the new trucks are a non issue.
