I don't know guys, I have had success using Alclad specially because I use it on small parts, when it comes to bumpers or anything bigger, I don't think there is anything out there that would do the job as well as the regular method of chroming. The base coat really has a lot to do with the effect on the part when it's alcladed, I have always used Testor's Gloss Black without any issues. Lately, what I have been doing is shooting the Alclad when my paint is tacky, not dry like a lot of people do. I am sure there are a lot of ways to do this, I have success doing it this way.
