Default Primer and the elements

I’m planning on restoring my 80 Trans Am. I have access to a big glass blaster so I’m going to do my fenders hood doors etc. since this will be bare metal then primed what primer will withstand the elements until the car gets completely painted. I wanted to strip it myself prime it then when I’m finished with it mechanically hand it over to a real body shop.

It really should be a good quality epoxy for bare metal. I use SPI brand, which runs about 200 for a gal of epoxy and a gallon of activator.. The most critical thing with the spi epoxy this time of year is metal temperature should not drop under a minimum of 65 degrees in the first 24 hours or it may never fully cure.Sand metal with sharp 80 grit on da first for best adhesion.
Their black epoxy has some uv resistance to it,Can be used permanently uncoated on underpinnings & for years on exterior parts in sunlight.With any epoxy, part of it's appeal is bonding things together & it has time windows to work within. Needs a day to dry for filler to be applied over, 2 for poly sprays, & within the first 7 days can be coated over without scuffing. After 7 days & especially months after, your best bond is achieved lightly sanding & giving a light fresh coat of epoxy before moving forwards with bodywork being done.
SPI epoxy is also glossy, which lets you better see what needs to be done & works as a guidecoat when you start sanding & removing the shine.
Here is a part I coated with it this week while still wet..
Also compatable with any shops other finishes.
