Im going to begin the body work on my 64 cuda soon, the car is in epoxy now and I have a couple of rust spots that I need to fix and then I will be beginning the body work.

I was wondering when it comes to straight body lines, if any one has some tips? Im looking to paint the car dark metallic grey so I know that body needs to be perfect!

thanks!
 
Well worth a watch, only takes a couple few minutes

wonder block, spray can of guide paint, do not push on the block, patience! When you start to rush walk away. I spent months getting my car straight. Walked away from it several times.
 
The link above is spot on. Been doing it for a living for a lot of years and I"ll still lay down tape for blocking even in the body filler stage.
 
You have to remember that the 1/4's are stationary where as the doors and fenders areadjustable. Start with the 1/4 to rear of door gap and adjust forward accordingly. It takes time and patience.
 
You need to use sharp paper. One thing that gets amateurs is not changing their paper enough when sanding. Beginners will (without even realizing it) start pressing harder on the block to compensate for their paper going dull. Pressing hard while sanding creates waves. When I do body work (I'm a professional) I end up with a pile of used paper on the floor. You also need to use the correct grit for what you are trying to accomplish. Have a supply of 40, 80, (120 I use this many people don't), and 150 or 180 for sanding your body filler.

Excellent tips, from a professional P & B guy, here. (Nice to see you comment, once in a while)

P.S.: That 120 tip, is probably why I back track too much.....)
 
Wow you guys thanks so much for all the tips!

I apprectiate everyone's comments! Thank you all for the help in guiding me as a hobbyist and mopar guy into the right direction so my car doesnt wave at me from across the street hahaha
 
I would add, that all primers/paints etc. shrink back to some extent, some worse than others. So if you aren't in a big hurry, prime it, block it, and let it sit for a few weeks. Then block it again. Let the primer shrink before putting the finish coat on.
 
are you asking lines or panels on lines I tape on one side prime - sand then repeat on the other side as many times as needed
