: : : Other than being more expensive, what are the pros and cons of John Deere spray can paint versus mixing/thinning and spray automotive style? I've sprayed a few small pieces after wet sanding that don't look too bad. Any advice is appreciated, thanks. My dealer tells me that Agriculture green (in spray can or brush) is basically the only green available since the removal of the lead bases that John Deere and others used in the past. The Classic green available is lighter and used on the newer garden series, am I being told correctly? Thanks again. : : You'll get a better finish with the spray gun; better coverage, and ultimately, more efficient use of the material. Spray cans tend to dry unevenly, and its difficult to control how fast they dry. Depending on the weather, you can change your thinner/reducer to compensate for a range of heat/humidity conditions. Not so with canned paints. If you haven't used a spray gun, that might make it more complicated to get a good finish, but all it takes is some practice. : : I have a hard time believing a retailer with a good paint mixing setup can't duplicate a color for your tractor (though I'll have to admit I haven't tried to buy tractor paint recently). : : One thing to consider is that even canned paints can usually be thinned and sprayed effectively if you're willing to experiment a bit. It's cheaper than all those spray cans! : They have to thin the material so much to get it to come out of the aerosol can that you get very little solids (resin and pigment)in a can. In other words you are buying mostly thinner (usually about 90%). This always results in the applicator getting a very thin coat which will begin to rust in a short period of time. I presume you are more interested in appearance than in corrosion resistance, however, you don't want your beautiful paint job to rust prematurely. Remember the key elements of a good paint job are surface preparation, primer, and adequate film thickness.
:each has its place. aerosol is good for refinishing a small repir, however to do body or componet painting your better off using gun.
