Tell them you are rejecting it under the sale of goods act, as it is an inferior quality to what is expected of a new car, and ask for a full refund.
I think the last time you asked the same question my answer was similar, keeping asking will not cure the problem or give you any more alternatives. You have only limited choices.
1) Respray as already offered, although not acceptable on a new car.
2) Replacement, which they have already offered with the same faults, unaccaptable.
3) Refund in full, using your legal rights ? Buy one elsewhere, or a different car.
Agree a reduction and live with the blemishes, unacceptable.
Or do nothing and learn to live with it, unacceptable to myself ------ your choice.
