It should be easier to sand!

Bad mistake.

That "glazing putty" is for filling-in tiny scratches.
It is NOT a substitute for BONDO, and you don't ever want to slap a bunch of it on there like you did on your spheres.
You made a mess.

"Glazing putty" is used AFTER the Bondo, to fill-in the tiny scratches.
And also: BEFORE you use the BONDO, you wanna scuff-up the surface with 80-grit sandpaper, so the bondo will adhere to the surface better.

The guy who recommended you do that is obviously not a paint & body man.

You actually WANT a hard surface. Whether it is "easy to sand" or not is not even the issue!

I do like your lamp nipples for the attachment. Nice to run the wires inside them. And good job on the larger washers.

Now GET THEM FINISHED and PAINTED so we can see what they look like!

Thanks A.M. I knew there was some thing wrong...

Mess or not, I'm having fun! sanding and mixing. Remember that some of the best ideas come from mistakes.

Bad or wrong I'm getting every body in the same boat, and for other newbies like me will learn how not to do it!

I did sand the spheres with 80-grit! before applying glazing putty

This glazing putty gets pretty hard and it's not easy to sand, I can't imagine "Bondo" (I have never worked with Bondo)

I like the lamp nipples too, they are strong and useful. Thanks.

Now to get them finished mmm.... that's going to take a while, you know me I'm very slow

BTW... I would like to finish the spheres with FLOCK, does any body know how to do it or where to buy the materials? or a DIY

These photos show my progress, after 20 minutes of sanding on each sphere and some test fit with the HL-70's and at the end next to a 6.5" Premier component, Huuug the HL-70 look so tiny, just for reference the spheres are 5" diameter. I finished the night work with a second layer of... you know that glazing putty more sanding over the weekend.
