Do NOT use anything Lacquer... lacquer was removed from the auto industry years and years ago and the new paint ar in no way compatable... you will have some seriously bad issues if you do.
I going to go out on a lim and say that what the above advice is based on experiances from BEFORE Lacquer was phased out
Hmmmm... looks like PeterG knows his stuff! I spent 5 years in a streetrodder'* garage building cars so I spent alot of time around laqcuer. I tried to convince the guy(once I learned myself) that laqcuer was a far inferior paint and that he should be using a BC/CC urethane or at the very least a SS urethane and epoxy primer. I read where lowrider posted:
I know autozone sells sprayable primer for paint guns. $39.99 for a good bit.
Correct me if I am wrong but this paint is Duplicolor and is laqcuer. I know becuase the streetrodder I was working with used it. You can't find laqcuer paint in very many places(though you can still find it) but you can still buy laqcuer primer. My suggestion to him was that if he were to use the said laqcuer primer, he would have moisture problems unless he mixed a bit of paint into the last coat. And yes, you are absolutely correct about laqcuer having reactions with other paint. It will not lift a cured urethane but it will lift an enamel in a hurry. So, yes, laqcuer primer is still available OTC but no, you shouldn't use it. I do not want to be misunderstood in my advice so I will finish off by saying that I recommend you use an epoxy primer for your base, a 2k high build on top of that if you have bodywork, and a urethane topcoat(either SS or BC/CC).
Yes, this is the best stuff available from what I've read. I have not personally used it but it is highly recommended. I use Dupont'* 5717S Metal Conditioner and combined with a scuff pad, it easily removes light surface rust and treats bare metal. If you decide to use either of these products you cannot use an etch primer on top of it so keep that in mind. I would use one of these products on the bare metal and follow it with an epoxy primer. I have had good results with this method. Good luck.
