Pros/Cons priming cab insides

Pages: (1/3) > >>

Just wondering if there are any pros or cons to priming the inside of the cab.  I've seen some prime bright white and others black, but I'm really just curious if it provides any true benefits or drawbacks.

I don't think there is any real advantage other than for aesthetics.  It's not like plywood or MDF will warp if you paint one side but not the other like a solid wood panel might.

SavannahLion:

About the only thing I can think of that might have a practical influence is whether you paint behind the marquee or not. Painting the cavity black might absorb some of the light, painting it pure white might help "push" some of that light forward.

The effect is probably negligible considering the volume of the space and the amount of light involved.

On new cabs, it is more of a "completeness" factor.

On old cabinets, it is done if the cabinet is extra skanky. It locks the skank in so your cabinet won't smell like rat pee once it is restored. ;D

Ive read somewhere (cant find it now) where MDF emits a chemical over time.
Priming the MDF supposedly seals it, keeping moisture out and the chemical in.
Thats the only reason I can think of, unless you want to open the back door and show off the innards of your cabinet, if thats the case, priming or painting inside might look more appealing.
