I already shot it and you're right, what a smell. Well now the wife is even further away from the garage.
My tips are to:
* thin it out per instructions and keep it very warm while using the extension tip to do the channels. I used the extension after spraying everything else, but it has to be very warm and well thinned to spray well. I got a big discharge from the channels later in the day under 80F heat.
uke:
* to do channels, insert as far as possible, then spray while pulling back.
* use the normal sprayer to do everything you can as it sprays much better.
* don't use this stuff until all your other work is done -- it's wax and will get all over you if you still need to do work in a treated area.
* spray very sparingly. thicker is not better, just more of a mess.
* keep a hot bucket of water available to keep the canister hot during application
* wear gloves and dust mask as the stuff is kindof nasty
Rust be gone,
Bill
