I am building a cedar home. I want to use one of the clear sealer
products to seal and protect the siding. We like the natural finish
and are considering one of the products that has a slight cedar tint
and had uv and mildew protection. I have heard that one of the best
products is the Behr No. 500 Premium Weatherproffing Wood Sealer &
Finish. It is available through our Lowes for about $30/gallon. I
noticed at WalMart the other day that they have another brand(forgot
to get the name) that has essentially the same ingredients but sells
for only $9/gallon.

I would really appreciate any advice about the best product for us to
use to preserve the finish on this siding. Thanks for any help.

You will be remiss if you don't include "Rez" brand Cedar stain/finish
in your consideration. I believe it's a Pittsburgh Paint product.

It is specifically designed for siding and similar exterior use.
