Hi, I am repainting a 70+ year old cedar siding house. I have done a good job of scraping and cleaning up the loose paint and peeling areas. I don't know if the present paint job is oil base or latex. My question is how do I tell which one it is and what should be used for a primer on the bare spots. As you put primer on it will cover some of the existing paint along with the bare area. My understanding is that putting oil base over latex is a 'nono', so should I use latex primer and forget about determining what the existing paint is. My feeling is that oil base primer is best if I can use it!!! MinnJim
