WD-40 caused no harm and helped prevent rust as SeaSlugs said.

When I hone cylinders I washer the walls with gas then I coat them with engine oil, wait a few hours, then wipe them down with white paper towels. The oil will lift out a lot of grit, so I keep repeating this oil and wipe part until the paper towels come out clean with clean motor oil only.
