I'm going to paint my old wood patio furniture. Since it will be in the sun, what type of paint should i use?

Should i use a base coat? Can I use a spray acrylic? In the past, the paint has always bubbled up on the furniture I kept in the sun.I'm going to paint my old wood patio furniture. Since it will be in the sun, what type of paint should i use?
It bubbled because your furniture wasn't dry and you trapped moisture in it or you painted in direct sun light that was too hot. What ever you do make sure you use a water based paint unless you know what kind was put on from the start you don't want to put oil based paint over water based BUT you can put water based over oil, oil based paint will tend to lift the water based paint off. Use some 100 grit paper and scuff up the areas where the paint has bubbled off and you can use an acrylic spray paint or acrylic paint with a brush just don't paint in direct sun it dries too fast. As far as curing most paints take 2 weeks to 30 days to fully cure, Good luck Les the painter If you do chose to put a urathane on please use a water based polyacrylic NOT oil based.I'm going to paint my old wood patio furniture.

It probably bubbled because you didn't prep the furniture properly. And it will also bubble if you put it out into the sun before the paint has completely cured. Leave the furniture in the shade for at least a good 24 hours, preferably longer to really let the paint dry good and hard. Clean the surfaces, then give everything a good, light sanding, then use a tack cloth to remove the dust. Then use a good primer coat to prep further. Use a paint, spray is better as you won't get brush strokes, that is made for exterior uses. Then seal it with a an exterior polyurethane. This should make for a much longer wearing surface.
