I discovered a dime sized chip on my hood. They got me the small bottles out quick and I fixed it. '97 Portofino Red here. I ended up putting a coat of clearcoat on the fix as well... I almost wish I haden't since that little spot now seems a little over-glossy. Try it without the clearcoat first IMO (if you don't have clearcoat to begin with).
I used the little bottles. Several light coats, follow the directions and its pretty easy.
