As said bolted on but be careful with the bolts, losen a bit then tighten back a bit. Do the bolts in stages but still expect a couple to snap. You need to remove the front bumper and also the inner wheel arch plastics. Not a difficult job but as for painting that is another story. Quick coat of paint or nice glossy matched to the rest of the paint work will cost a lot more money. Get the, painted before fitting.
