Generally you get what you pay for. We used shutter renu over 8 years ago on our faded gray shutters and they still look like the day we treated them. We also bought their siding product for our faded siding and restored our siding a year later and it still looks good. Good luck.

We have never tried shutter saver. We used vinyl renu which is made by the same people that make shutter renu (we also looked at Vistalone who makes a similar product but didnt choose them). We had allot of shutters and it was cheaper buying larger units of vinyl renew than the shutter renu packaged kit. Vinyl Renu was more money than shutter saver but they have great reviews and a contractor friend told us about it and said he uses it in his business. We figured for all the work of climbing on ladders and cleaning we didnt want to have to do it again in 3-4 years so we used vinyl renu which seems to be the longest lasting product (or lease the product with the longest claims).
