First time posting to this forum.I gotta 59 Studebaker Lark 4dr.Not real sure exactly what I'm gonna do with it yet,just kinda day by day.Car is in pretty bad shape.I just got done welding in a new floor.Still gotta work on the trunk and a few other areas.I've got the front end off and I'm doing some body work to it.Now that I got you up to speed with my project,here in a few days I'm gonna be done with the front grill area of the car.I want to put something on it to keep it from getting surface rust while I do work on the fenders and the rest of the car.Sometimes I get freebies from some friends of mine that work in varies industries and I came across a quart of Duplicolor primer/sealer.I am just wondering if this stuff will be good to go straight onto bare metal or is it the wrong product altogether for what I need?I heard from some ppl that it is a laqcuar and that it won't last and will just cause me problems down the road when I go to paint the car.Is there any truth to this or are they just being d-bags?Any help will be greatly appercitated cause I don't know jack about paint and primers.
