Like other products rattle can primers come in different qualities. BASF has several that are high quality primers but there is a lot more poor quality rattle can products than good ones? U-Pol (http://autobodystore.net/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=PRI) makes several good rattle can primers and you can also buy a quart of real primer, mix it with hardner and reducer and spray it out of a Preval Sprayer (http://autobodystore.net/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=P2).

because a foundation has to support all that is put on top of it. Keept that thought in mind when thinking about primers. Stay away from the department store Duplicolor primers and such. They may beat bare metal showing but should be sanded off prior to any serious good quality paint work.
I will say this though about rattlecan primers; Rustoleum recently came out with a black primer intended for use over rust metal surfaces. I experimented with this stuff that past year on some rusted iron candle holders my wife has in the yard. I wire brushed them, wiped with a dry papertowel and sprayed them with just the primer (no topcoat). Been 10 months and they sit outside in rain, snow, ice and sun. No signs of breakdown. Still doubt I would use this on my car though. Henry
