Compatibility

Q: A friend told me that he used nitrocellulose sanding sealer on wood, and then finished it over with an automotive two part clear coat. Does this seem possible? To me it just sounds like the two different systems will not go together.
A: You are correct in worrying about incompatible systems, but as luck would have it, the two your friend used, while not ideal, are compatible. He’ll be fine as long as he did not pile on too much soft sanding sealer below the harder topcoat.
