I over estimated the amount of stripper I needed. I am keeping a quart for future projects and selling the un-opened quart.
The product is Soy Strip.

This product works very well on everything except bottom paint. Paint it on, leave it sit, and 2 hours latter it can be scraped right off.
A quart should be able to do both side of a 20 footer.
My cost was $21.95 plus shipping.
Your cost $20.00 and I will ship free.
