Yes and no. You can stain the doors with this product. However, I would not expect it to last very long, more so if the doors are in the direct sun. This product is designed to dive deep into the wood in order to provide lasting protection. Sapele wood is similar to Mahogany. It has a density of about 640 kg/m3 or about 40 pounds per cubic foot. For a hardwood with that density, you might want to consider using a Hardwood Wiping Stain like this: Hardwood Wiping Wood Stain.
