I was going to add this to the "3M Paint Defender" thread that HandA started, but apparently that thread has been removed? (huh) (confused)
Anyway... This weekend, I tried the 3M Paint Defender spray out on the new car. I did not buy the application kit, but would tend to say now, that it may well be worth getting, if only for the trigger holder (and maybe the reel of tape). My trigger fingers were really hurting by the time I finished! (I kept swapping left to right hands, which just made
both fingers ache.)
By far the most difficulty was in taping off. I used newspaper but it's more painful to position and tape down than plastic sheet would be. The spray itself is very 'wet' (large droplets, heavy flow, small spread), nothing like regular paint sprays, so the spray doesn't move very far unless you're in the wind - but then not a good idea to do this in the wind anyway!
I applied a ~20" wide strip across the hood an a couple of pieces on the front of the fenders and pretty much emptied the can. So the 10 square foot coverage is pretty accurate. Looked horrible when freshly sprayed - milky and irregular - but dried (several hours) to a clear smooth film. So all's good. Obviously I've no idea about longevity yet, but it's a decently thick film, though I doubt it's anywhere near as good or as strong as clear-bra.
One tip if you do this... mask
first (with a double line as the instructions say) BEFORE applying the wax that comes with the can! Otherwise (don't ask) the waxed surface is
so slick that neither masking tape nor blue tape will stick down. (gah)
So, here's a couple of application photos. I have no post-dry photos yet as I did this Saturday and it's been raining ever since, so the car's been stuck in the garage... They warn you not to let it get wet for a couple of days after application (the stuff is water-based and needs to cure well, or the finish can suffer, apparently). Will add final photos later.
These are taken freshly after spray and after the first edge layers of blue tape have been removed...
