I wanna see the post blocking picks. Use long blocks and light pressure and change the paper often. Yeah right, like Im am telling you anything LOL Im sure you know exactly what you are doing.
Dont cheat, show all the highs and lows

That might determine the final color too (light or dark), unless you are ready for another round with the build primer.
But just looking at the flat primer thats there she looks pretty flat. The block will reveal ALL though. I found this out.
When I blocked my car I ran into some low and high spots. It was an eye opener, one that I didnt want really. I have alot of work to do.
I hope you get a nice flat sand. Cant wait to see the post sanding pics. JR
