Have Snapper 1650 with plastic dash and control covers that are faded/worn from being outside in weather. They have some cracks, which I think I can glue/repair once off. Wondering if some majic compound to bring back the black color or if painting is only way? Will about any paint work or need special plastic type? It's not vynil, so thinking any paint should work w/out melting. Would you use flat, satin or gloss? Satin seems more likely I'm thinking, but maybe the Gloss would just dull after awhile and look OK?
