It won't work as well as a fixed mount but you should be OK to around 50W or so with a decent 4"-6" diameter mag mount. I'd definitely not be putting more than 100W through a mag mount though. You'd find when you'd exceeded the capacitive coupling of the mount when you removed it and found little burn marks on the paint from the arcing.

MOGVZ , I must have got lucky , Iv'e read this & checked mine a few times , I run & Old King Bee 250 ( On High most of the time ) & I have no Burn/Arc marks . If I didn't live rural I probably wouldn't need High , but most of the people I chat with from the woods are over 30 miles away .
At what power level you experience it depends on the capacitive coupling ability of the mag mount to the metal it is attached to. The better the capacitive coupling the more power it can handle before you overcome it and start to get the arcing. The mag mount I use is 6" in diameter, has an aluminium sheet on the bottom of it going across the whole area and a very thin rubber boot is placed on top of that which I doubt is even a millimetre or 1/25ths of an inch thick. It will have a better capacitive coupling to the roof than one which hasn't got that sheet and/or uses a thicker rubber boot on the base. Some mag mounts will use three or four magnets connected by a metal plate and they're better even still at running more power.
Many of the cheap ones it is literally the outer rim of the mag mount which is metal with nothing but empty space and a small magnet in the middle. They're the ones which are most likely to give you issues when running any power. If you have one of those you can improve it by putting a sheet of fairly thick kitchen foil across the bottom under the rubber boot.

UPS brought me a Sirio Performer 5000 today. I took an old Nmo adapter and replaced my Larsen with it. I ordered the 6 inch mag mount also since I needed a mount with SO239. I have other uses for it.
This antenna is built nice. Definitely seems to work better than my Larsen. Has much wider bandwidth. It had gnarly match right out of the box. No adjustment needed. I did take each set screw out and applied blue loc-tite. I like it. It even has an Led that lights up when you talk. Weeeeeee

Seen't that. I kinda like it. Maybe they should make a coil with a lighted lava lamp. That'd be cool. 8 inches, though. Damn!
Well, I guess I’ll have to dig around for my giant triple-mag mount. Disassemble and do some high-speed polishing worthy of a bullhauler KW out of Nebraska.
Then the more-or-less chrome PRESIDENT TEXAS antenna.
And some LED spotlights. Or just a whip tip that pulses.

I have a triple mag mount with NMO. I have the adapter for UHF. I can run it on my Cherokee, but it's lopsided. The raised roof strengthening panels won't all the 3rd magnet to fully seat. Keeping it for my next vehicle. I wish they'd use those one magnets (can't recall the name) they are strong as all get out.
LOL, I'm the Mack Daddy. Far as I know, I'm the only base in town. Last dude died few years back. He was old school CB'er. He made all his antennas, base and mobile. There's other mobile ops, but no bases. Village of 1500.
I have been running Wilson 5000 mag mount antennas for 21 years now on 4 different company cars. I currently run a barefoot OmegaForce S45 HP. I ran a DeltaForce radio with numerous amplifiers for 18 years and never had a single problem. Biggest amplifier was a 667 but most were just 2 pill amplifiers. Had no choice since they were company cars but a mag mount worked fine.
I have experienced similar results with the Wilson 5000. I ran a straight 6 pill with a Galaxy 95T2 driving it and never had a problem.
Currently using the W5000 mag mount with a Rci-69ffb4 and having good results.
Did yours have the tension-locking-flip-arm down near the base?
On the mag mounts...I admit that i have been running a DX500V into my Wilson 5000. I plan to drill the hole, but it’s been working so well I haven’t bothered yet. I also want to try a Sirio, but the Wilson already whacks a bunch of trees.
I love my Stryker but wish it had that handle so you could lay it down . I'm not over aggressive just run my " Old " 2 pill King Bee 250 on Max all the time Np's so far . But changed a bad patch cord , I ordered a 12" but my old one was an 18" I haven't used the amp since I haven't checked my Swr's , Probably won't make much of a difference , just being careful .
