After some reflexion on the subject I intend (as I don't have 3 guys painting) to after
1. primer red oxide
2. paint doors interior(visible interior) and dash (black in this case) and then mask them to avoid overspray
3. trunk interior, doors, windscreen, rear glass, sills surrounds with overspray to interior (some visible overspray)
3.5 not decide if here or on 5.
4. body exterior with overspray to underneath, doors exterior and trunk lid (carefull to not spoil all surround body areas already painted)
5. Engine bay on black with overspray only to underneath
6. all other parts painted off the car
Always not sure I'm doing it correctly but...
PS: on my ?65 convertible and fastback door front area (looking from front fender) is not painted just primer and overspray, have you the same?
