When painting woodwork - that is actually wood and it needs to be primed... make SURE that you use the right product.
I mistakenly used a primer for UNfinished wood instead of a primer for oil based surfaces...
It is a bad thing - it takes hours and HOURS and lots and lots of scrubbing and undoing to fix it.
Fortunately, I found out my mistake before I painted EVERYTHING... I realized it when the paint that I was putting over the primer kept rolling up and falling off. HUMMMMMM dummy me just kept painting and painting and REpainting.
Now, I'm scrubbing and scrubbing and scrapping and scrapping - my hands hurt, my arms hurt, my back hurts.
Hope you learn something here and never make the same mistake.
