Chipped oil-based trim: touch-up technique?
Our vintage house has loads of white oil-based trim, and it's fairly brittle. We need to start touching it up, and would hope to avoid completely repainting. There's also some new trim in the mix, already primed with acrylic primer. Can anyone with experience recommend a method? And specifically,
Is it better to sand, spackle and then use the oil-based paint again?
Do I need to use primer if I'm going to continue with the oil-based paint? Must it be oil-based primer?
Can I sand, fill and then use an acrylic primer, followed by latex paint? (I have good matches for both acrylic and oil paints)
Thanks for your insights before I tackle this big job!
