If it is possible, I would use BPI® Barsplicer System (http://www.barsplice.com/products_index.html) or LENTON® FORM SAVER Dowel Bars (http://www.erico.com/products.asp?folderid=45) to avoid exposing rebars for months.
-----Original Message-----Try Z-Bar by Gerdau Ameristeel. www.gerdauameristeel.com/zbar there are other corrosion resistant reinforcing steel available. Some of the names are escaping me though...

Hi,We are constructing a metro station outer structure and due to work schedule some part of main rebars (above slab level) need to stay open (non-cast) for about 4-5 months in winter season.In order to prevent the rebars which will stay in open air for long time until cast, I am looking for an economical product where I can spray (or paint) the rebars which will prevent rebars from corrosion and also will not affect bonding when concrete is cast several months later. I know that there are some rebars which are pre-coated before installation but in my case I need post-coating or something after partially cast.I will appreciate if anyone can advise me such product (coating or paint, or grout, etc) where I can find some application references and bonding strength will not be affected.Thanks in advance,Oz
