Any Experience with this Seller for Touch up Paint?

Looking for a source for touch up paint. I would prefer a single stage enamel and I’d really like a small non-aerosol quantity. Use is for small chips and scratches made during assembly (thankfully limited to low visibility areas so far). I found these guys on eBay. Any experience or suggestions for sources?
