for their distributers or to order online.
If you paint without treatment you'll have more rust and corrosion by week's end.
Thanks Lyman. I checked Ace Hardware and the big box stores and could not find the products you recommend. I guess the climate, here in the Southeast Washington desert makes for slow sales of rust treatments. I did, however, find a Permatex product that employs the same chemistry. Our weather was pretty reasonable yesterday and today so I pulled out the chassis batteries and refurbished the upper drawer and upper part of the battery compartment. Great improvement wiith the rust treatment ahead of the paint. As predicted, I am already seeing rust through the paint applied last week without treatment. Re-doing the lower part of the compartment is now on my to-do list for this spring. Thanks again for the tip.
