Bummer! Good word for it.
I thought about using shellac as an undercoat. Thanks for the advice on the primer/sealer version. I have used plain shellac as a finish coat before. I am not sure if it is de-waxed though, I would just get the primer version.
It didn’t take me long to remember remember the oil spill from a long time ago. The smell is a dead give-away... 90w gear oil. The smell of that stuff is memorable.
Also good advice on making a poultice (I wonder how many people are familiar with that word...
). I had already thought of just putting some “speedy dry” (basically clay cat litter) on it and let it sit. But soaking it with paint thinner first and then doing that might work. It seems that would draw it out better.
I did soak it with paint thinner and then blotted it. This worked to some extent. But I didn’t soak it for very long as I was afraid of the paint thinner drawing the oil further into the MDF.
So, I will continue on with this advice and will let you know how well I do.
Thanks for posting back with the suggestions...
BTW - I really like the teal colored speakers - nice job on them.
