|What are pros and cons of Butyl putty vs Linseed oil putty?

Linseed oil putty goes hard after a long time.
Butyl putty stays soft for ages.




Mine went hard, wrinkled and got eaten by birds



Acrylic is better than either of them



Thanks all for comments so far. How does acrylic compare to the others
mentioned?

Acrylic goes hard enough to take paint in a couple of hours and stays
flexible enough not to crack and fall out in a couple of years. Linseed
putty depends on the paint not allowing the oil to dry, which in turn
depends on the thickness and degree of exposure to the elements. The
butyl stuff stays too tacky for a good paint finish.
I haven't seen it on sale as "acrylic putty" for a while but general
purpose acrylic sealants "suitable for glazing" would be ok.
