You guys think its ok to pressure wash under my 71 grabber thats been sitting over 20 years. Also looking for shifter linkage for a c4 automatic. What year mustang will fit?
I Pressure washed the underside of mine shortly after purchase, and that was with a 3400 PSI 4 GPM pump. It was not turned up all the way, and I tried to keep the tip 2" away from stuff. Nothing got ruined and it was quite clean afterward. Maybe try an area to see if the undercoating stays put? It didnt bother mine.
