I have some surface rust peeking through some spots that I have primered. What happens if I brush some ospho on those spots? Will it seal?
Or, am I better off just going down to bare metal and applying it? |

Is it a grey or red primer???
It's porous... (IMG:style_emoticons/default/barf.gif) Per the primer, you would be degrading the primer with the acid in the ospho and it may affect the color coat adhesion or disintegrate the primer under the color coat. Use self etching or epoxy primer as a base coat. They are NOT porous. Then you can add primer surfacer later..... |
