The one good thing about attempting to install the vinyl top yourself is this, the top is about $150, the cement is about $40. So for around $200 and a good 8-10 hour day of work, you can save yourself $400-???? in labor and most likely end up with a better job IMO. You just have to do LOTS of prep work and be patient when doing this job and have a good helper who is willing and able to do exactly what you tell him/her (good luck with this one). LOL When working with contact cement not a good time for a know it all/smart a$$ helper/assistant!!!
