Hope are well known for making shit seat post clamps

Which brand of carbon assembly paste are you using?
I was using a Weldtite one for a short time before I realised that the chonky particles did close to nothing. I ordered the Park Tool carbon paste which improved thing. The particles are finer and more plentiful, so I assume they have an easier time getting where they need to be.

Been told not to use normal grease as that can cause the epoxy to to swell.
EDIT Thought it was a carbon frame and seat post hence using carbon assembly paste.
Got an on one lurcher that I've just bought a hope bolt on seat clamp to replace a quick release. Got some carbon assembly paste from Halfords tho not used it yet https://www.halfords.com/cycling/bike-maintenance/bike-lube/halfords-carbon-gripper-paste-10g-651233.html
@MCamb are some model hope clamps better than others?

Could try adding something like a BBB PostFix BSP-97 Seat Clamp. I have one on my gravel bike.

Hope seatclamps are rubbish. Alu bolt and nut, the bolt usually gives way eventually.
It is also a non standard thread, M7 which is more prevalent on cars than bicycles.

My seatpost (31.6mm) keeps slipping. I am using a Hope clamp (35mm) and grease (carbon with particles) and my post still slips.
I cleaned the post with isopropanol, cleaned the seat tube with isopropanol. Applied a small amount of regular (white) grease on the inside of the clamp, alligned with the slits in the back of the frame (seat tube). Added a drop of loctite to the clamp-bolt. Greased the post generously with (carbon) grease, torqued the clamp to spec and... this mofo still keeps slipping.
Any ideas on a sturdier/better clamp? Maybe using (even) better grease?
