Front door stain advice
I recently bought a home that the front door is stained a reddish color. They left the stain and it's a gel stain.
The door is "mahogany textured fibreglass door"
I am wanting to stain it a walnut color... If I sand it down, I fear the wood grain texture will go away which I want to keep.... Ideas on how to go about this project? Stain to use? Etc. I would do both the indoor and exterior side.
TIA.
