Key differences

Chemistry differs: OSI QUAD MAX is a base: silane modified polymer, A2 is a moisture cure hybrid polymer. Confirm paint and substrate requirements before switching.
A2 is paintable: yes, after full cure. Where the joint is an exterior weatherseal rather than a painted one, look at null instead.
