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? |

OSPHO IS PHOSPHORIC ACID !!! You do the science. The stuff is made for bare metal only adn should be put on bare metal ONLY !!!! You used a cheap primer that does not etch and you either need to strip it and apply an etching primer or spot strip it, re-prime those spots and get a good sealer on it. You get what you pay for (IMG:style_emoticons/default/shades.gif) IF you do use Ospho FOLLOW THE FREEKIN DIRECTIONS. It is not a brush on and paint over product. It WILL cause you problems if not properly neutralized.

I read the bottle's directions 5 times, trying to make sure I use it properly. I AM SORRY IF THEY CAN'T ANSWER EVERY QUESTION ON A QUART BOTTLE!! Geez.... who pissed in your Wheaties this morning. |
