I agree that lettering enamels aren’t what they used to be, but have found that One Shot Lettering Enamel seems to hold up the best. I always stir the paint thoroughly to make sure the dryers are mixed in well, never just
“shake” the can. I’ve never had a fading issue after just a few months. BUT I don’t work in a warm sunny climate and UV rays do take a heavy toll on paint, especially alkyd enamel. Maintenance does play a role and if the owner of the vehicle is lax on washing and maybe a little waxing then the lettering also suffers.

You can add either 1-shot Metallic Gold or
1 Shot Metallic Silver. These will add body to the
paint without diluting the shine and durability

Over the years I have found that adding hardener does help. I never sprayed in my shop but I had friends at body shops that would clear coat projects that warranted the extra cost. Lasts for years.

Would love your thoughts, please comment.x
