Paint Sealers

Automotive Paint Sealers what they do .
A sealer is used to improve the uniformity and gloss of the final colour coat, to fill flatting scratches, and to improve colour hold-out. It can also be used as a ground coat to aid the final colour match. Sealers should not be expected to act as 'isolators', to prevent wrinkling of an old paint film under the action of strong lacquer solvents, or to stop bleeding through of a previous colour coat. Special products called 'bleeding inhibitor sealers' are available to stop bleeding.

A point to note about these is that they give a poorer hold-out under colour coats than the standard sealers.
