The Other 68 Dart Resto Project

Looking real good ! Still on my first go around with blocking. I know I'll be doing the entire car at least once more, most likley 2 more times.

Im doing 180 grit dry right now, 80 seems way to coarse for blocking primer. I think Im going to do another coat of high build and hit it with 180 again before blocking the last coat with 400 wet.

Once thing is for sure, Buying some nice blocks made a huge difference. I bought a 6 pack of Dura-Blocks for $30 off of ebay. Worth every penny.

If you think you are going to spray more than one coat of a good filler primer (featherfill G2 or Slicksand), then go coarser than 180, I used 120 grit on the bad areas, then blocked with a 220 on the straight areas, followed up with a red scotchbrite pad (about 350 grit) for the smooth areas. Once you are certain you have it smooth, go over everything with 400 and finish with gray (fine) scotchbrite pads (about 600 grit). Then you can spray the primer/sealer. I used epoxy mixed as a sealer (w/20% reducer). Next will be paint. I am going to paint the door jambs and hood & trunk this weekend.

FYI, want to practice before you spray the whole car, do the outside of the hood or trunk lid. WHAT!?!? No, i'm not nuts. If you screw up and have to sand it back off, the hood or trunk are flat panels and are easy and fast to sand.
