Does anyone know of good way to paint PVC metallic gold with spray cans?
We usually have our metallic gold sprayed with Matthews paint and have had excellent results, but our spray painter doesn't have time to do it.
We'll be painting slim letters, so there are no broad areas, but we want to do a good looking, long lasting job.
Anyone had success?

PVC is tough to get most paints to bond to, Paul. I think I'd be tempted to spray them with Krylon Fusion (find a yellow or gold tone). Then, using that for a "primer", spray your metallic gold over that.

I would suggest using an automotive type such as duplicolor or touch up spray bomb from a parts house after using a plastic bumper type primer. the pigments in the automotive color will be mica flakes instead of the cheap bronzing powders used in the gold in spray bombs and will not turn green after a few weeks.

Krylon Fusion bonds quite well to PVC, clean it well and scuff with a fine Scotchbrite pad. It takes about a week for it to cure and during this time it can be scratched fairly easy, but once it cures it bonds very well.

Prep it with PPG One Choice or X-I-M adhesion promoter and spray with a good quality gold aerosol.
If you can, hit it with clear coat to add some shine and protect it.

I have used Krylon brass and it makes a better gold look than the gold.

I've had good luck with the Automotive touch up paints like Duplicolor or Near Match. When you say PVC, what product are you referring to? I think there is a big difference in adhesion with something like Sintra or PVC foam boards versus PVC products that are not manufactured for the sign industry. Be cautious ith the Krylon Paints, many of them are for indoor use only, and I agree with using mica based metallics over metallic powders which will tarnish and turn ugly in a short period.

Last time I did the Krylon Brass for outside use I cleared over it with 1-shot spray can clear and it has been about 5 years and I go by them everyday on my way home and they still shine.

We ended up using Matthews acrylic urethane with less than satisfactory results.
The edges soaked up so much paint that the faces ended up with too much build up near the edges. A borderline acceptable job.
I'm planning to wet sand them and use a high build primer on them before putting the finish coat on. Does this sound reasonable?
