biloxi_dad Posted February 23, 2022 Share Posted February 23, 2022 A while back there was a post on product(s) used to counter rust on the battery compartment tray. I've searched the various topics on this forum and can't find it. One in particular used a paint/primer and a type board (if memory serves correctly) to protect the tray. Looking for some input/suggestions. TIA Link to comment Share on other sites More sharing options...

DavidL Posted February 23, 2022 Share Posted February 23, 2022 (edited) Most important is to clean the metal. I garden hose wash to get rid of majority of acid. Then power wash (put eye protection on as there may be acid in the water). Then, treat with baking soda to neutralize any remaining acid. Clean again after a few minutes. Dry. Then wire wheel or better yet, sand blast. Fix any corrosion spots (weld, or even body plastic if cosmetics are important). Wire wheel any welds. Mask bearings Prime with a quality auto primer Top coat. Can use Por15 if you like. Reasemble. grease bearings. Put all back together. Clean electrical connections. Rewire. Label all wires.

Martinvz Posted February 23, 2022 Share Posted February 23, 2022 Several years ago I had to do the same. Only I did rot use regular primer. I used a rattle can of black rust converter that also acts as a primer. So far after about 6 years, it has held up very well and I am very satisfied.

Tom Whitlow Posted February 24, 2022 Share Posted February 24, 2022 I've also had good luck with Rust Reformer paint. Link to comment Share on other sites More sharing options...
Ivylog Posted February 24, 2022 Share Posted February 24, 2022 Phosphoric acid Is the active ingredient in all the rust removers (and in sodas) and I buy it by the gallon below. It’s worth painting with the paint below after properly prepping…or just use AGM batteries and now Lithium. 1 Link to comment Share on other sites More sharing options...
DoubleL Posted February 24, 2022 Share Posted February 24, 2022 Yeah I used phosporic acid on mine. Then I coated with two part urethane paint that I had left over from another project. See the pho. tos. They are out of order finished is first, the rust then after acid. I also used epoxy to seal the corners where the acid could seep down between the frame.

Tom Whitlow Posted February 24, 2022 Share Posted February 24, 2022 I second the Lithium battery suggestion. Far superior batteries. I converted my golf cart to Lithium. No more corrosion. No more water refilling. Link to comment Share on other sites More sharing options...
veraken Posted February 26, 2022 Share Posted February 26, 2022 I used a product called Chassis Saver. You still have to wire brush and remove all loose rust. I found that Chassis Saver was easy to apply and did not need the prep coat. You can get it on Amazonhttps://magnetpaints.com/underbody.asp Link to comment Share on other sites More sharing options...

Good advice, except use POR15 directly on the rusty metal. That's what it's made for, and it works very well. As long as it's not exposed to direct sunlight, it is fine by itself. If you want a different look, POR-15 makes a tie-coat primer that allows topcoating with another paint. I've been using POR-15 products for decades, and their products are excellent for their intended purpose.

I'd use it over the POR-15 and tie-coat primer. I'm actually not sure of the acid resistance of POR-15.

Steven P Posted March 6, 2022 Share Posted March 6, 2022 When I pulled mine, I used OSPHO rust remover as directed and painted with a truck bed spray paint giving a little more protection. 1 Link to comment Share on other sites More sharing options...
