I’m nailing up Miratek trim with a coil nailer and am having trouble with mushrooming of the material…if I cut the loose stuff out and putty, will it hold? any suggestions?

Never used Miratek, but found that trim head screws make for a better job than nails on PVC trim.
what do you putty the holes with?
Bondo below eye level, any acrylic latex spackle above eye level.
There's a product called Bond-N-Fill that's supposed to be the cat's meow for both gluing and filling but I haven't used it yet.
thanks! anyone else know anything about Miratek? it's nice to work, except for the mushrooming...
One option with Miratec is to drive the nail heads down just snug with the surface, but not penetrating into it, or, just flush with the surface, and in either case you just paint over the nail heads. Of course this leaves the nail heads visible but works OK particularly if you are putting the wood grained side out. If you don't like that look, counter sink them slightly and cover with an exterior wood filler type putty or exterior rated spackle. The problem with this later method is that the nail spots need to be sanded and spot primed. Most people just drive the nail heads down snug.
I have used Bondo with this material, and the down side is that it is a PITA to work with - what with the mixing and the limited working time.
have used alot of Miratek and not sure what the painter used specifically for it ...
but do know same painter uses Dap33 as much as possible as a nail hole filler.
so ... betting he filled the Miratek with Dap33 before he sanded/painted.

Azak now makes an epoxy filler for holes and large cracks $ seams. It's rather pricey, about $29 for a tube and it needs to used in one shot unless you buy extra nozzles for the tube at $1.00 a piece. It mixes the two parts right in the nozzles. If you're doing a high profile job I would use it where seen, otherwise I go with the Bondo. I am restoring some Victorian fretwork and built up posts right now and some of it is done in Azak so I picked up a tube of the filler just yesterday.
I'll let you know.
