A "gilt" is an object which has had a thin layer of metal applied to it for decorative reasons.
In the case of this quote, "gilt" is probably referring to the layer of metal itself. The quote can thus be taken to mean that if one does more than admire an idol, or any sort of false deity or other such esteemed object, it becomes apparent that the divinity and wonder was just a thin layer spread upon something far less pleasant.
Putting the obvious matter of idols and false gods aside and bringing it to a more worldly view, it can show that we tend to romanticize things that are unobtainable and that as soon as we obtain them their flaws are revealed and they cease to be that glorious thing we once saw them as and become something far more plain.
This quote means that by associating with or touching things or people that are considered superficial or morally corrupt, one's own character and morals may become tainted or compromised. It warns against getting involved with negative influences that could impact one's own integrity.
A homophone of gilt is guilt.
