Re: Etch Primer
If I've read your post correctly, you are repainting the entire boot lid?
Yes, the lid doesn't completely need to be taken back to bare metal for primer to be used, however, where the paint is still in situ, I would recommend keying the surface with a scotchpad or some other light abrasive surface before priming.
Personally, I would only apply the etch primer then to the bare metal; let that dry & lightly rub it back, then completely prime the lid using 'regular' primer, to ensure a consistent foundation surface, before applying basecoat & lacquer.
Do you have the correct colour of primer for your car? The colour of the primer strongly influences the shade of the basecoat subsequently applied (making it lighter or darker).
This is another reason for only using the black etch for spot repairs, then covering with primer - it's much less likely to give a patchy colour finish.
If you can give me the paintcode for your car, I can tell you what colour of primer you must use.
This job should never be complete - the day I think I've done it all, is the day I resign.
