Thanks for Moving it Nige!!
Thanks for confirming the basics of the process
Sorry i apologise, i got my terminology mixed up, by basecoat i meant solid colour. It's going to be just 1 colour, viper red via ppg turbo range (2 pack). In terms of the stripe, as it already had a white stripe down the middle, i didn't want the chance of the primer being lighter in that section, leading to a lighter shade of red where the old stripe was. My plan is to vinyl new twin stripes, still cant decide on black or white, hence the vinyl
I have been told if sticking to the same colour, there's no need to primer, that's why i was after some clarity over the primer on the existing paint as just sealing it then painting would definately lead to a lighter shade of red. Hope that makes sense!
Still working on the repairs, got a couple of pics to put up still.
Cheers!!

Hi Ray, to quote:-

Ok, there's a few things to consider here, some painters feel that if you apply a white basecoat under a red then the red becomes more "vibrant or "brighter". The reasoning being that the white base will allow less coats of red to be applied to cover the primer & that the red will, in doing so appear lighter (hope that makes sense). eg if you spray a panel white & then apply 2 coats of red, the red will still be slightly transparent, allowing the white to "lighten" the paint. Add another 2 coats of paint & that red will then appear darker, as the red becomes less transluscent & full colour coverage is achieved.
As I say, some painters like to paint cars this way. Personally if i pick a colour i like, as in the Audi "Brilliant red" on mine, then I want it to look like that colour, not a slightly lighter colour of Audi "Brilliant red". Normally if a white base is applied & then a red over the top with just a couple of coats applied then it's nescessary to clear lacquer the whole lot to get enough coverage to flat back & polish.
The down side of this is that you don't have a true colour, but a lighter shade, which in the event of any damage becomes more awkward to colour match. I'm not one for spraying a white base to be honest, if you look at the pics of my car in primer, I had the primer tinted red. Although this takes on a slightly pinkish colour, the Audi red covered well & a full "true" colour was achieved after just 2 coats (although quite a few more coats followed)

if you're staying with a similar colour then you're correct in that you don't need to primer or seal the whole car (you shouldn't need to seal it if the paints been on there for a good while & that you don't break through into the paint beneath). You will however, as a precaution, need to seal any repairs or areas that "break through" into the layers of paint beneath. you must prime over the sealer though as the sealer doesn't offer good adhesion to colour coats.
Hope that helps
