Anyone ever drill out their spray gun tip?

Have you used either of the products I've mentioned? It'll be my first time. They seem like they're easier to use for beginners rather than lathering up panels full of body filler and hacking away.
I used to live in Ranch Cordova when I was stationed at Mather AFB. They both work fine, but I prefer the Evercoat G2. it sprays on and sands off BEAUTIFULLY. I use a 2.2, but a 2.0 would work. If the body work is good, you'll be amazed at how good it looks after block sanding.

However do not think that a heavy polyester primer will replace good body work. A paint job will never look better than the surface prep. You still need to use body filler (use Evercoat Rage Gold; it sands a ZILLION times better than BONDO) and LOTS of elbow grease. Electric or air sanders are fine, but the Dura Block sanding blocks I mention below with 80 grit will work fine. Just don't "lather" too much filler on at a time. The more you put on, the more you have to sand off. Thinner layers are best. You should also consider a Glazing Putty (Evercoat of course). It will fill pin holes and minor imperfections very well. It is thinner than body filler and sands easily. I usually block it with 180 and then 220. No way to get a good paint job without buying some materials

You REALLY should buy a set of sanding blocks; Dura Blocks are about the best, and they are quite cheap. Then buy 80, 180, 220, 320 and 400 grit sandpaper in the 2.5" rolls. Get the peel off adhesive back kind. I buy the brand that Eastwood sells. The Brand name is something like Rhyno. I honestly think it works better than the much more expensive 3M Gold. Then apply a light film of guide coat over the cured Polyester (this is a MUST) and start with the 220 grit in a cross hatch pattern. Be careful on edges. The guide coat will make low spots stick out like a sore thumb. Anyway, block with 220 until all the orange peal is gone. Then switch to 320, and use it until the 220 sanding scratches are gone (won't take nearly as long as the 220). Then smooth it out with 400. Then I use 320 wet followed by 400 wet. When the surface is wet you can really see how the paint will look. Good Luck. Feel free to send me a PM if you have any questions.
