Are many days I have been looking for impregnating agent and then I stumbled through Amazon on the Fa. Norax. Since the cleaning is as important as before the impregnation itself, I found in these spray bottles exactly what I needed to get my awning to treat. Cleaned and then impregnated, thanks to ultra-fast delivery (1 day), I could already do everything on 26.07.13 (thanks also to the weather, which dried within an hour, the marquee of the cleaning). Both the cleaning and the impregnation was super easy by the spray bottle and mist the distributed well and covering all areas. Now the long-term effect must only occur then this Produnkt is optimal.
