3 in 1 Primers

[cwb90]

Are the 3 in 1 primers any good and do they perform as advertised? My car has been sanded to bare metal and would like to know if should use one of them or stick to the traditional primers. I'm considering the Transtar brand, Clausen "All You Need" or the Clausen Z Chrome Rust Defender. If anyone has used these products I'd like to hear your thoughts on them. I will be using Dupont ChromaBase / Clearcoat as my final topcoat.
Thanks,

Clint

if your project is a high end, you should avoid transtar, i use almost every transtar products but i actually dont doing high end jobs, transtar are very good products but i think the prices or quality of the top coat you will use dont match with medium end products...
