I went through this when I repainted the 2a. Can be difficult, but a few points that help.
1. Make sure there are no burrs on the hole.
2. Use good quality grommets - some of the cheap ones are too stiff to go in easily.
3. Make sure the ones you have are the right size, not metric/imperial mismatch or designed for a different thickness metal.
4. Use a lubricant. I found rubber grease the most useful, but alternatives include soapy water and talc powder or graphite powder (messy)
5. As a last resort a tool such as Dave suggests, but this should not be necessary.
