This is your gig and while the products they've mention do work they're not the end all.
I think a question that needs to be asked is; do you really need to so a 2 step correction on every vehicle. If not take a hard look at
Meguiar's D151.
Meguiars Paint Reconditioning Cream D151
"Meguiar's Paint Reconditioning Cream D151 is aggressive enough to remove severe defects, yet gentle enough to produce a durable swirl free finish.
Change Meguiar's Paint Reconditioning Cream D151's performance by simply adjusting your method of application. Change from a cutting pad to a light cutting pad, for example, to remove imperfections without holograms. Use the Meguiar's G110 Dual Action Polisher for light defect removal and a rotary buffer for heavier paint correction. Meguiar's Paint Reconditioning Cream D151 is the fully adjustable polish!
You can even apply Meguiar's Paint Reconditioning Cream D151 by hand for ultra gentle swirl removal with absolutely no holograms."
I personally prefer the
Menzerna paint correction products over the ones offered by Meguiar's.
