Will plastic glides installed over carpeted boat trailer bunks take anti-fouling paint off of pontoons?

I have a pontoon boat that I have on a trailer with carpeted bunks. The boat is used in salt water and has expensive anti-fouling paint applied.The boat is a bitch to launch & recover due to the friction between the pontoons and the carpet. I want to install glides (slides) over the carpet but the glide manufactures don't know if the paint will be worn off. Has anybody had experience with this? Mike
