Is it ok to top HD Speed with a sealant?

Do you think this black pad application would remove a previous few month old sealant?

Good question... and probably hard to know for sure. If the goal is to remove a previous applied sealant I would use a more aggressive pad - white or orange, and use more of them. This will engage the abrasives in Speed and remove the old sealant.

Thread bump alert - so I was looking for the latest in AIOs and durability, came across this thread. I like HD Speed for my wife's car and my son's car because they don't care that much. I detail them with a clay/HD Speed once/year. I used HD Speed on my wife's car some time in the summer of 2018, no additional wax/sealant until this year's detail except several touch-less drive-thru washes (I at least got my wife to use touchless). I did this year's detail on Mon, June 24. Same deal, nothing since then except touchless washes. So it's after midnight, I'm reading this thread, trying to find info on how long AIOs last, and I realize I've got a test case in my garage. Why not? It's after midnight, but I just played soccer and am a little jacked up. I go out and wash half of the CRV's hood with ONR. Then I spray it with distilled water. It's beading water beautifully (not that beading water is the end all, just read that thread too). That's four months. Is this because the HD Speed is still protecting, or because I used ONR to clean it?

P.S. Daily commute, trips, the car averages nearly 20,000 miles/yr, so probably around 6,000 miles since the HD Speed, garage-kept and underground parking at work, not babied, but not worst case scenario either.
