GF Arm-R-Seal is the topcoat follow up to Seal-A-Cell (it’s the red labeled can). Comes in Gloss, Semi-Gloss and Satin. Same wipe on ease, builds a finish. I would seal the insides of the cabinet to keep the amount of humidity absorbed by the wood stable on both sides of the board to avoid excessive movement (cupping, etc). But I would recommend (for the millionth time) Zinnser Sealcoat Dewaxed shellac. This can be padded on with a cloth rubber (wad of cloth with an overwrapped cloth, making sure no wrinkles or seams are visible. The reason why, you ask rather than more of the same? Shellac builds fast, drys fast, and has no odor. It can be rubbed out to match the gloss level of your topcoat by using increasing grits, and you can rub out in a day or so. Oil finishes take longer to cure, and will leave an odor inside the cabinet (or drawer) that lingers for a long, long time. My 2ยข.

-- "Bordnerizing" perfectly good lumber for over a decade.
