If you’ve seen the TapePro Stealth Sander floating around and wondered why opinions are mixed, Phil from PRC Taping explains it well in this quick review.
Most of the confusion stems from how the head is designed to run in an internal corner.
We’ve embedded Phil’s video below, plus the key takeaways (straight from his walkthrough).
What the Stealth Sander actually does:
Phil’s first point is the big one:
- The Stealth Sander has two different sides/angles
- One side is 85°, and the other side is 95°
- They’re made to do two different jobs inside the corner
- One side sands the inside apex of the corner
- The other side sands more of the outside edge
So if you’re using it like a “standard” flat-sanding head, it’s going to feel strange, but that’s not what it’s built for.
When Phil uses it (and when he doesn’t)
Phil is clear about how he uses it:
- He uses the Stealth Sander specifically for finish sanding
- He doesn’t pre-sand with it
In his workflow, it’s a finishing tool designed to clean up and feather the corner nicely without chewing it out.
The pads: “like a sponge in your corner”
Phil calls out the pads as a standout part of the system.
He explains that the Stealth Sander pads basically mimic a sponge inside your corner, so you don’t need to “light check with a sponge” the way a lot of guys do — the pad does that finishing job for you.
Setup is simple (ball adapter + pole)
Phil runs through the setup:
- Put your ball adapter on your pole
- Slap it straight onto the Stealth Sander
- Once it’s on, you can clearly see how:
- one side is hitting the apex
- and the other side is hitting the edge
That’s the whole point of the design.
The biggest tip: let the sander do the work
This is the part that’ll save you grief if you’re new to it.
Phil says the key is: don’t force it.
- If you’re pushing too hard
- Or you’re feeling a lot of friction
- That’s a sign you’re going way too hard
You want the sander to do the work.
Phil’s finishing flow (before he goes to the Stealth Sander)
Phil mentions that before he runs the Stealth Sander, he’ll often:
- go around with his Planex or his Mirka
- and hit the edges of the angles
- then he’ll “run to the Stealth Sander” to finish it off
After that, he’ll check it with a light.
The result: clean feathered edges (without over-sanding)
Phil’s wrap-up is that the Stealth Sander is an effective way to get a clean finish on inside corners. He also notes it:
- doesn’t over sand
- leaves a beautiful finish
- and feathers the edges nicely
If you’ve been on the fence because of mixed reviews, this video is a good one to watch — it shows exactly why it behaves the way it does, and how to get the best result from it.
