Assembly compound on folding bike seatpost.

I am at the max for my folding bike weight limit. When I ride the seatpost tends to slip and I am worried about over tightening the quick releases as I have already bent one. I am considering using an assembly paste such as Park Tool SAC-2.

1- Has anyone on this forum used an assembly paste on their bike's seatpost to prevent slipping?
2- What are possible disadvantages?
3- Will an assembly paste work on a part that is not clamped for the long term? (I will readjust the seatpost every time I fold and unfold the bicycle.)

Regards,

Buy a cheap seatpost quick release clamp for a few dollars to fit your diameter seatpost. File off the protruding part and place it on your seatpost so that the seat post cannot slide down.
Here is a picture. Zoom in on base of seatpost.

That's a cool idea. What do you do when you want to fold? Do you just slide it up and have some sort of mark to return it to the correct position?

I would line up the 2nd qr with the 1st for a bit of symmetry.

Yes I open it up and slide it up before folding. Brompton has inserts that set seat maximum which is set when I unfold. Then I lower the clamp and its at same spot again.

Yes I open it up and slide it up before folding. To unfold lift the seat to max height. Brompton has inserts that set seat maximum. Then I lower the clamp lock it and its at same spot again.

Schwinnsta,
Thanks for the advice. The seatpost on my Xootr Swift is listed as 34mm. What size clamp would I need? Without any bike shops near me the closest I could find on the internet was a Giant brand clamp listed as 35mm.

Also I am still very interested in the opinion of anyone who has used or uses assembly paste on their seatpost.

Regards,
