The water stops the acid. If you are going over it with another coating, you want to stop the acid, maaan.

Great info in this thread. I am staring to close up my longs, firewall bulkhead and some other cavities, so was reviewing all this info.
The rinse-with-water-and-let-dry part of the process scares me. I wouldn't have considered it, except that at least three guys in this thread with 100x more experience than me are doing it. Running a water hose through my longs (IMG:style_emoticons/default/unsure.gif). Guess I'll be doing that as well. For Scotty B., I thought I read that in your opinion rust encapsulators (not converters) are snakeoil, don't bother, but here you say that's how you finish off the process. Is that true just for cavities, where other options are limited? Or maybe what you are saying is that they are okay if you get rid off all the rust first, just don't use them to actually encapsulate rust? |

I like to use a MAPP torch to carefully heat all the nooks, crannies, and especially seams after applying paint prep, metal ready, and water to dry these areas out. Leaving water sitting in your seams for a few days will ensure they will rust. John |

QUOTE(FourBlades @ May 12 2011, 12:21 PM)  heat all the nooks, crannies, and especially seams after applying paint prep, metal ready, and water to dry these areas out. YUP I have used a paint stripping heat gun to dry out the acid rinse water, to soften and remove the tar on the floorboards, and to help remove gunk and seam sealer from all nooks and crannies. Focused heat is your friend when drying out the prep liquids! I have been doing the interior rustoration piece-meal, but this Sunday I am planning a full-on attack with Wurth Metal Ready. It was not cheap, but has both the acid and zinc in it. Then, Wurth self-etch primer, then paint (then seam sealer?). |

A little flash oxidation will help some of the coatings adhere. I use the wands to blow the cavities dry with compressed air.
