it gives crazy peel with even the primer lol. but well.. ill put it this way.. i put 2 coats of primer on the hood of a 65 Mustang i was going to block out... i used almost an entire quart on that ALONE. puts alot on but gives plenty of meat to block out. i was dry blocking with 100 grit and it still took a while to break through. that gun rocks. try Ebay to get one.. its often cheaper than a jobber. i saved about $50 that way and the gun was brand new. i have a 1.3mm Sata KLC-B that i use for a basecoat gun ( technically its a primer gun but damn it works good ). i have my 1.4mm Harbor Freight gun thats regulated to minimal primer work and nothing else... my 2.3mm bad boy Cobalt and my 1.2mm Sharpe Cobalt that i use for clearcoats. yes a 1.2 and a 2.3 are in my stable... i run both extremes with the tip sizes for full sized guns lol.
