My '50 "B" is BC/CC on all the green and single stage on the yellow. Been painting 35 yrs professionally. Clear coat does not know whats at the bottom. As long as you use the required "system" to get from the base metal up to the base and the clear,you will NOT have any problems. I believe what you may have heard in the past is to not use BC/CC on cast because it will shine too much and the cast won't have thatrough look to it. What happens is this. Some have applied their epoxy,then a few coats of primer surfacer,then sanded the surfacer(because you have to)then thier base coat(2 coats) then two or three coats of clear. Let's face it,we all know that the thicker the film build,the less durable the paint job.Just put on one good coat of epoxy,enough color to completely hide and then one coat of clear. It will still look like cast,but by doing the complete tractor the same,it will always age the same. I BC/CC everything because it is such a fool proof and easy way to get a state of the art job that will last forever.Another reason,price out a gallon of color against a gallon of clear! I used exactly 2 quarts of green on my "B". Base color is ultra high solids,doesn't take much to cover. The other reason I use it is in the auto bussiness it's the only way you can match paint when the Ins' co. doesn't pay you to paint the whole car just because you replaced a fender.Won't go into it all here.It is my opinion that any bad experiences you hear about pertaining to BC/CC are from the "chemists" that insist on mixing and matching different brands of catylist and clear and color because someone told them that it was cheaper and worked for them. Happens all the time,just read paint and body forum,you will see. As far as shine goes,single stage will shine the same as BC/CC if both are sprayed properly.BC/CC is just more user-friendly and cheaper.Remember, we are talking urethanes here.Some will argue that it is all overkill for a tractor,and that plain old synthetic enamel is plenty good. They maybe right,assuming the tractor will never see sun,rain,gasoline,bird droppings,fallen leaves that bake in the sun etc. At the end of your question you said single stage enamel.The first part of your question said BC/CC. Since BC/CC refers to urethanes,I will assume that you meant single stage urethane and not single stage enamel. Just do it all the same,that paint don't know the difference between sheet metal or cast.Good Luck on your "B",I'm sure it will look great.Keep us posted.
