Thanks. I like that Royale you're working on. As far as masking the yellow was concerned, that was no necessary. All the yellow panels were separate inserts so I sprayed the body all black, sprayed the yellow inserts, then glued them in place. Funny about the specific shade of yellow too. I used a GM touch up paint back then from the auto supply store. It was an exact match to the original yellow on the 1:1 Bugatti Royale.
