Assuming you would be going with a non-metallic red, I would not go with a black sealer. I would suggest a lighter gray sealer. If one is not available, you can mix a black and white sealer to make a lighter gray sealer.
You could do your stripes first or last. Personally, I would probably do them last. you just have to make sure you mask off the rest of the car very good to keep the metallic sparkles from getting on the red.
if you did the stripes last, just mask off your stripes, then spray a couple thin coats of black first before your charcoal. This will make the charcoal cover quicker.
If you sprayed the complete car in a sealer first, then sprayed the stripes, then decide to do the red color the next day, some sealers may give you a problem.
Soooo.....
If you spray the red first
spray your lighter gray sealer (assuming it's a brighter to medium solid red)
spray your red
mask off your stripes (cover the complete car except the stripes)
Spray a couple coats of black or a dark gray (not sealer, just some base you can make up. This needs to be a 'solid' color)
Spray your stripes (keeping in mind, that you need to keep the edge to a minimum. The darker gray or the black sealer will help speed up the actual charcoal metallic coverage)
remove your mask
clearcoat complete car
If you spray your stripes first
spray your lighter gray sealer (assuming it's a brighter to medium solid red)
spray an area where the stripes would go in a black or darker gray (do not mask off the stripes, just spray an area bigger than where the stripes would go)
mask up the stripes
important! Spray a lighter gray base about the same color as the sealer (close as possible)
spray your red
clearcoat
In both cases, the darker the charcoal metallic, the darker the base should be (i.e. use a black for a very dark charcoal metallic. Use a medium gray sealer if you are using a medium charcoal metallic)
Again, I would still do the red first if it was me, but it's totally up to you!
