I just repainted my '68 with Sherwin William's economy line. I used BC/CC. The reducers, primers, and clear were "Refinisher's Select" and the base was "4th Dimension". I was very happy with the product, especially compared to their regular line.
If would use a 2K primer, it will fill 80 grti scratches, which means you can save a LOT of time on bondo and other "heavy duty" body work.
My total order ended up being about $500. This was for 3 quarts of Chevy Victory Red (reds are about the most expensive color), 1 quart of white, 1 gal of 2K primer, 2 quarts of etch prime, all reducers and catalysts, prep solvent, body filler (Rage Gold is great stuff!), DA paper, wet/dry paper, paint suit, respirator, and a few other things. As you can see, unless you already have a well sanded coat of primer down, the other stuff adds up FAST. If you were going to paint just the outside and no top, 2 quarts of base and clear will probably get it. Yellow should run you around $25-30 a quart for the 4th dim. stuff and clear with hardner about $45-50.
I ordered all of my stuff from Paints Plus at
www. paintsplus.com. Ask for Gino and tell him Ben Munson sent you. He is very knowledgeable and will only sell you what you want/need.
Cheers,
