Greetings Tony P.
I have sold and/or installed hunderds, if not thousands of squares of Mainstreet vinyl siding and I have been very happy with it.
It is all in the installation. any siding not hung right, will not perform properly.
If you read down thru the post, you will see many post about vinyl siding.
I prefer Wolverine Benchmark but, Wolverine and Certaiteed are owned by the same company and they stand behind thier products.
I would recomend that you visit the Vinyl Siding Institute website @ www.vinylsiding.com
