I'm kind of bummed. I took my 29 roadster to my buddy's body shop to get primed, two states and 500 miles away. I brought him the primer, which I ordered as red oxide. When the painter opened the can it was gray but, since it was what I had brought, he shot it anyway. Grey's not bad; it's just what not what I had in mind. I need help getting my head around the color change. Anybody got some photos of traditional rods looking good in grey primer to pick me up?
Do you propose to leave panels in primer or paint later? Acrylic primer is porous and will over time absorb moisture from the air depending on where you live. If exposed to the elements it may surface rust from underneath the top coat and eventually bleed through. If 2 pack primer, it is not porous and won't allow moisture through. Not sure about the non solvent [water] based paints these days. My body shell and hang on panels car was shot in 2 pak primer many years ago and is still holding up well. The delay in laying down colour is another story.
My Tudor is primer. It's been on there for 8 odd years. It has rusted through the primer in many places and this year it's getting paint. I drive the car all the time regardless of weather but the car lives in the garage when not being driven. The primer was for lack of want/need for paint but now it's time. Cliff Ramsdell
Primer not what you wanted ! Try explaining to a painter he got you the wrong color after he said it not his fault. My 56 was almost a medium metallic blue because paint shop said that was Nassau Blue to the painter. We had a good fight over that one until he finally understand GM used the name Nassau thru varying years and models.
Don't put any spray bomb stuff on it unless you want to either sand it all back off prior to painting, or live with it forever. Most any spray bomb paint will soften when exposed to the solvents in modern automotive paints and then you've got a major mess to deal with.
