Q: Does the clean diamond finish clear coat come in a matte or satin finish?
A: At this time, the DiamondFinish Clear comes in a Gloss Finish. However, you can lightly sand the DiamondFinish Clear with steel wool after 24 hours to knock down the sheen.
Q: Can diamond finish clear be used over rust seal? I'm looking to use rust seal as a color base coat on some automotive components (steering rack, transmission, differential...etc) and use clear to provide the UV protective layer/topcoat
A: We do not recommend putting DiamondFinish Clear over RustSeal because although DiamondFinish Clear is absolutely UV stable, DiamondFinish Clear does not block the UV rays from getting through to the RustSeal. Over an extended period of time, DiamondFinish Clear can delaminate from RustSeal when exposed to prolonged sunlight.
We always recommend a solid color UV stable top coat paint (such as BlackTop or KBS Maxx) over RustSeal if RustSeal will be exposed to sunlight.
