Hi. I am replacing various panels on my project. This is happening over a period of time. I need to prime the new panels for protection. Ultimately (in the course of time) I intend to have a full respray.

My question is -: What type of primer can I use that will not affect the final respray? I have not decided on the final finish yet but quite possibly a candy or pearlescent paint.

My intent is to do the base coat & prep myself but get a paintshop to topcoat & clearcoat.

Thanks.

First of all, make sure that wherever you are planning on having it painted is ok with you doing the prep yourself.

 

a vast majority of painters will not touch a car that has been prepped by someone else, especially an amateur.

 

As for covering the bare panels/joins/welds and seams, use a zinc rich primer, the higher zinc content the better.

 

i have done this on mine and bare metaled the panels as i go so everywhere will just have a thin coat of zinc and then when it comes to prep, it's just a nice blank canvas instead of layers and layers of primer in all manor of odd colours etc.

 

Remember, normal primers including red oxide (unless it's the real thing) are porous so it's not a good idea to leave areas in regular primer for extended periods of time, especially outside in all weathers as the primer will soak up the moisture like a sponge and rust the metal under the paint.

Thanks Ben. I just want to be sure that by covering the panels and bare metal it wont react with any final painting. I know there are numerous types (acrylic, 2 pack etc.) as opposed to the cellulose I used in a previous life.

The Mini is in my garage not outside so further rusting is not a big problem.

You shouldn't have any trouble with reactions but you can get isolators like barcoat which will seal any old incompatible paints

I have converted to epoxy primer as I find it really good and is water proof for restorations where not being over coated straight away.

Depends on the paint shop might worth asking what acceptable to them however I would tend to use epoxy as above but being a painter myself I would have to re prime it and guide coat and flat it again even if it was high builded and flated before so I could give guarantee as for repair I would do the repair you have to do etch prime high build that area and let the person who going to paint it to put the bar coat on and more primer on But agin it all comes down to who is painting it
