QUICK ANSWERS

Common questions

Is gray the best all-around shade?

It is a versatile neutral choice, but the topcoat system's recommended ground shade takes priority.

Can I use it over bare metal?

Use only on prepared metal substrates and within the corrosion-protection process Transtar specifies.

Will it fill sanding scratches?

It provides fill and build, but the repair must still be finished to the scratch range allowed by the TDS.
