Cluster Housing Refurb

So I got all the rivets undone with both heat and small help from dremel. Came out pretty well, but one post broke. I think I can jb weld that back anyway. Couldn't get any of the paint to budge with conventional chemicals. So then I put on one coat of oven cleaner yesterday. Here is the result. Pretty good for one try. Another coat or 2 and I think it should all be stripped. Anyone know if oven cleaner is acid or base and what I should use to neutralize before the paint process?
