We have one of the versions of Louisiana Pacific siding on our home, and it is deteriorating. We would like to replace it and then depending on the siding choice, paint it. Looking for the most maintenance free solution. 1st: What is the best siding choice? Hardie Plank (concrete siding), Vinyl, brick, stucco etc... 2nd: What is the best choice for paint. I have read a lot about Vinyl Paint and Ceramic Paint even a paint additive called POLYMATRx (http://www.northstarvinyl.com/polymatrx.asp). These are supposed to be guaranteed for 25 years or more. What is the real deal on these products, are they worth the money? Has anyone used either the Viynl paint or the paint additive? Do they work as promised. Any and all help and information would be appreciated.
