Hello,
Is a sanding sealer necessary for hardwood? Does not stain and polyurathane seal the wood enough? When should a sanding sealer be used?

Sanding sealer is great for use under varnish but can only be used with select polyurathanes.
Sanding sealer seals, dries fast and is easy to sand. After the first coat is sanded the next coats [sealer or varnish] require just a light sanding.
Poly doesn't seal the grain as well so it requires a little more sanding after more coats. Poly dries harder [and slower] and requires more effort to sand.

Marksr,
Thanks, I will test this product out to see the differance between using and not using it on wood for staining. I was told by a salesman to use it prior to staining a fiberglass door with gel stain. But it did not seem correct and I asked mfg respresentatives if it was and they claim to never hear of it being recommended.

I'm not sure if I ever stained a fiberglass door or not. Usually sealer goes on after stain. When staining pine and some other soft woods it is sometimes necesarry to use a sealer wash [sealer+50% thinner] or a wood conditioner, but I never heard of anyone doing it on fiberglass.
Not all sales people are familiar with the products they sell. This is especially true at big box stores.

marksr,
I am old enough to remember when sales clerks knew what they were talking about. But I guess those days are long gone.
Recently, I visited a small lumber yard and the clerk and I were discussing stairs and their associated parts and he pointed at a skirtboard and called it a stringer. This same clerk said he could order solid oak tread (non sandwich type) so that the grain would match just like the risers I bought. But his other associate (who may have been the owner) said that was not so and all treads come sandwiched and some have matching grain and some don't.
Well even if they can be purchased somewhere, the premium for them would price them too high.
