A trick a neighbor of mine, who was a painter for 40 years, told me a great trick for painting over crazing paint. Mix Fixall with the paint. This dries like stucco filling the cracks yet the paint slows the drying time down enough to work with it.

I did this on a wooden garage doors and they maintained their semi-gloss finish for years without problems. I sold the house several years after doing this so I’m not sure how long it actually lasted. My neighbor said he used this technique on front porches with a little sand (for anti-skid) with great success and longevity.
