The AFB's look great! We really need a Holley single 4 barrel with the "LeMans" float bowls for the single 4 barrel intake used on hemis for NASCAR racing. Also the carb used by most during the late 60's for NASCAR. Same carb came on a Shelby GT-350 and the single 4 barrel 427 Cobra.
What I do is tape the break with Tamiya masking tape and then take some 3M blue 1 inch tape and some kitchen cling wrap. I tear off about a foot of the Cling wrap, lay the edge on the counter top and take the blue tape and tape the edge, leaving about half the width of the tape. I tape that to the Tamiya tape and wrap the cling around the nose, taking time to make sure nothing is exposed. Then I spray. Keeps the chances of paint being pulled by the tape to a minimum.
I feel your pain! I once painted a 57 Chevy Black Widow 6 times, always something ruined the paint job. Tried different paints, different techniques and nothing seemed to come out right. I finally pained it with Tamiya spray cans and took it to our monthly club meeting and took home the monthly prize against about 20 other builds. I even threw the body across the room at one point, glad it found a soft landing spot Bottom line, hang in there, it can get better!
Actually all the tires in the Hall of Fame kit are terrible, with the Lotus and Watson being the worst. The correct tires for the Lotus and Watson are available from Indycals and come with decals for the correct markings. The original kit tires were still not correct for the 1963 cars as raced. Indycals measured, photographed and 3D printed the masters for the correct 63 tires. It was the only year for that particular tire design.
The Bronco is one I want, used to have a nice 70 model, wish I still had it! One of my favorite kits from recently is the 57 Chevy Black Widow, Well done kit, I do wish they'd throw in a back seat and a 6 cylinder engine to make a plain old 150. Still, a great kit. A new type Corvette may be a popular one, nicest 'vette in decades. Keep it up Revell
