Now, if you tell me that car has been outside for 20 years this whole time then you might have a point.

I drove that for a winter car for quite a few years until I bought my first truck.It has seen plenty of out side , but is also well cared for & It has an acrylic enamel finish ..I have 4 of these that were painted using lacquer primer for a surfacer . They all look today like they did when I painted them , the other 3 are painted in lacquer paint as well ..

BTW I do this for a living . I don't use lacquer primer any more due to the fact that it is not what it used to be . (EPA ect)

The point of my post was , if you are just beginning, save as much money as you can on materials , you may have to do it a few times to get what you want..

Technology has changed as the years go by , but OE's have never used epoxy primer , & to this day do not ..

Maybe you can explain that to me ...? BTW ,, OE's do repairs as needed to the cars on the line ,... still no epoxy .....

Primers

Comparing OE paint methods, and what a typical shop or indiviual can do, is apples and oranges. Electrostatic application systems and baking methods arent common. The first appilcation, over bare metal, should be an adhesion promoting type of primer. It is usually an epoxy based primer but, can be an acid based type (Duponts Variprime) as well. Body filler is recut back to bare metal, sanded, then topped with a high build primer surfacer. Products change over time and what someone could get 10 years ago, may or may not be available any longer. Find a reputable system and stay within the system from primer to top coat. For the amount of labor involved in doing a quality paint job, trying to save yourself a few bucks will generally bite you.
