Message You need to go up higher on the grits and maybe even a wet sand at the. Block where you can because you are going to have tons of high and low spots. The way you are going...you are going to have a horrible paint job unless you plan on doing some major prep from here.

Since you've already done the damage, now you have to reverse all of it now.

1) I'd hit it with something like a 320 all around. Spend about 2-3 hours doing this right.

2) Blow it all out. Move up to a 600 and spend another 2-3 hours cleaning all this again.

3) Blow it all out with compressed air again. Red scuff pad the whole thing again. Take about another hour to do this all good.

4) Hit the whole thing with prep all and clean it all up.

5) You will probably need to shoot a light primer to even out some of the damage you've already done. Let it cure overnight considering we are in the winter months.

6) Scuff pad everything again. Blow it all out. And prep all it again.

7) Spend a few hours masking everything correctly and finally paint.
