I have been working on bringing my 2cv back to life and am getting to the filling/sanding bit ( www.2cvellekay.weebly.com). I have been using simoniz spray paint acrylic primer in parts. I didn't realise I could get cellulose paint but I have and this is probably the most suitable as I think this is what is on left on the car (originally blue & resprayed black in 2000). Some places I look say that the primer is suitable with all automotive paints including cellulose, does anyone know if this is the case? I dont want to have to strip what I have done off if I dont have to. I want to put cellulose primer on over what I have done then the topcoat. This is going to be a working car, I'm not looking for show finish, just the best I can get without going mad.
