Thread: Paint problem steel rims

I painted six steel rims last Monday (that'd be nine days ago), sprayed with an undercoat and killrust top coat.

This afternoon I went to load them up as my new tyres were waiting at Bob Janes and the paint was basically still liquid. (It's had nine days drying time.) What could possibly have gone wrong here? I'm suspecting a compatibility problem because the two I didn't undercoat were much better (but still not hard dry) compared to the rest. How can I go about stripping them back?

In the end I had to just get them put onto factory alloys, but I'll swap over for sure.

Temperature is a factor.

I recall painting a trailer with killrust and it was only just around the minimum temp recommended for painting but got colder overnight. The paint formed a skin but was still very soft under the skin. It took a "coupla days" before the paint skin did not move over the soft paint under the skin. After summer the paint hardened.

You will probably find that the ones without undercoat just have a thinner coat of paint and have dried a bit faster.
