A word on oil based finishes
Would like to mention that alkyd or oil based finishes still out perform acrylics hand down, especially for outdoor use. The way the oil based finishes work is they are based on drying oils. These are vegetable or seed oils that harden by polymerizing and oxidizing in the air. They may dry to the touch in hours but can take up to 8 weeks to fully cure!
Rustoleum Clear Enamel Spray
It is an oil based clear. In my experience, it is quite durable but it is not as clear as krylon as it is enamel. The reason is that Rustoleum has UV inhibers to protect the pigments from fading in sunlight. For this, I recommend it for outdoor garden sculptures as a finish over oil based paint.
UPDATE: At this point when I use spray paint, I have been using Rustoleum products almost exclusively as the spray consistency is much better and the covering power is superior. The difference in quality between Rustoleum and Krylon is most noticable in the primer. The Krylon can jusy spits and sputters like a third of the time while the Rustoleum sprays smooth and covers quick.
