After first primer, before first gloss
Or after first gloss, then on for a second coat?
Ancillary question, I am using 2 pack, how many coats recommended?
Many thanks

Paint the car first. Paint the seam covers off the car then fit.
Solid colour or metallic?? Solid colour 3 decent coats should do it or a fourth coat for colour sanding. Metallic i cant comment on as never applied that.
My clubby i ended up with six coats but that was down to some thin patches and some runs that i sorted out. That was only my second time that i have done a full respray. (Project Paddy in my signature) And that was 2k.

My dad (30 years experience on the gun) applies a dust coat and one decent coat then a heavy one, regardless of paint and always has great results with no need to do any polishing, just a denib(removing the high spots).
In my opinion If it's a metallic, get a professional to do the job, with a standard colour you can have a go yourself. It's a black art though!

If using 2k, then 3 coats is usually more than enough.
2k metallic requires a clear coat and the colour is applied as a base coat.
If this is the case, then the amount of coats of base depends on the colour and how well it covers.
most colours require 3 full coats and a drop coat which is a light dusting after the last full coat and after complete coverage and this allows the metallic to stand up better.
you need to observe flash off times between coats.
When applying the clear, I use 2 full coats and no more. But this is because the product I use specifies not to exceed 2.
If you want more, you can do what is called flow coating and that is where you paint the car, allow to harden, flat back the clear coat and then apply a further 2 coats before final flatting and polishing.
Putting loads and loads of coats on doesn't offer any more protection and only serves to make the paint look heavy and in the case of 2k direct gloss, it can actually soften lines and you loose the crispness of the lines.
Everyone has their own methods and the above is just mine.

Are you reusing the old seam covers or fitting new ones? If fitting new ones, make sure they actually fit first. The guy who sorted the body on my car didn't bother checking they fit, assumed they would, and got the them all painted when the shell was done. Turns out they're miles out. Now I have to spend ages grinding and bending the already painted seam covers to get them to even remotely fit. I might end up making my own for the front end because the fit is so bad. Will end up having to repaint them... AFAIK the ones I have are the BMH made ones.

I'll second that advice. My new covers were way out as well and required a lot of work and filler to sort them.
Don't use the usual barbed clips to attach them, the clips dig straight through the paint to the metal. Use a mastic to stick them on after all the painting and polishing is done, particularly if you plan to use a powered mop for any final work.
