However, being a carbon post in a carbon frame, I didn't bother to apply carbon paste. Having ridden through a very wet winter, it meant that my post was very firmly jammed in the seat tube. I couldn't twist it, even remotely. I read on a cycling forum to give this product a go. Looking at the previous reviews, I didn't hold out much hope. However, after spraying a liberal amount around the seat clamp area and leaving it for a short while, the post came out with ease. I couldn't believe how effective it was!! I can't speak for it's other uses, but if you have a seatpost you cant remove, this product is fantastic. 29 June 2013Rated 1 out of 5 by MRSman Shock Spray I did not find this product useful, The freeze spary offerred by Loctitie for a few pounds more is far better. 03 March 2012Rated 2 out of 5 by decoxx Halfords Shock & Unlock It promises to unlock carbon parts but it didn't work in my case. 20 February 2012
