b.The solvent can attack and lift or wrinkle the underlying coating
c.It reduces drying time safely
d.It has no effect at all

Aggressive solvents in some topcoats can soften and lift an incompatible underlying film, causing wrinkling or delamination. Painters check compatibility and recoat windows on the product data sheets before combining systems. When in doubt, a test area or a compatible primer prevents failures.
