Other idea was get black styrofoam and just whittle and shave it down into an aero shape then 3m sticky or gorilla glue it on
Any ideas would be helpful
Also they generate a lot of wind noise, so I’ll be trying a few vortex generators too later on

Foam is good idea, it can be glassed over to create a permanent fairing.
Creating an 'armature' and laying up papier mache to create a slightly undersized form which can be fiber-glassed would also work. Once it's glassed, submerge it in water to disintegrate the form leaving only the shell.
Same for drywall compound over a hardware-cloth or expanded metal lath armature, ditto. I've done both.
