if you try the r/c antenna trick, actually even the gumout tubed worked pretty good but wasnt as long.. the r/w tube was about a foot long etc.. you must remember to spray the can upside down with the tube still on it to clear it out between coats.. or it will plug as the stuff solids up.. this stuff is nice.. it sprays in easy like wd40 almost.. but as the stuff evaporates it leaves behind a waxy oil base film.. you cant count on being able to spray eveything directly tho so you must work slowly in stages fogging it in, without doing too much at once and causing it to run all over and make a mess, possibly plugging some of the tubes and/or causing pooling ...
