well just gunna spit it out here we go.I have my truck project going in the drive way and almost down to bare metal bare in most spots .i have etch primer to spray once i get all metal but its takin several days and in the meantime i am gettin flash rust.I still have several days untill i shoot it but then i still need to primer then paint what can i do to buy some time and keep the rust away will the etch primer help with the surface rust outside for awhile or should i get a primer sealer and not worry about the etch stuff as it sayes only for bare metal and feather edged old paint or can i spray it on big sheets of old paint also theres some sort of deal with filler and etching primer?just seems like alot to do i have the winshield out and in order to put it back for awhile i need to at least have sealer if not paint there before i put it back.so etch and prime and seal and paint the area around the winshield then install and paint the rest later?I am so confused .I see spraytech u painted the firewall first and put the motor in .I am tryin to kinda do the same thing finish the firewall and winshield rot then put it together and finish the body work and paint but mother nature wants that metal back and I dont want that to happen
