does teak give more structural support than replacement alternatives??

[jwilson]

Please listen to Tranona - in my foolish youth I bought a boat with saturated and rotting balsa core in relatively small parts of the deck and coachroof. I fixed it from the underside, which was about the most truly horrible job I have ever done. Doing it again I'd work from the top, and accept you need to refinish the deck afterwards. As you want fake teak on top anyway the refinishing is easy compared to restoring patterned non-slip which is what I was trying to keep intact.

Personally if you have to have the teak look I'd rather have the fake. But you really don't want to spend money on teak or fake teak and put it onto a compromised structure......
