Advice for repairing rust holes

[doug]

Hello everyone, I’m hoping for some advice on repairing rust holes on the outer tub of my ge filter flo washer using por 15, bondo and fiberglass patches. I’ve already cleaned and prepped the rust areas. Would I apply the por 15 first let it dry and then go to the bondo? Also do I apply one coat of bondo to the surface an let it dry before putting the fiberglass patch on? Thanks in advance -Doug

Bondo

As far as fillers go the all time best I used was something called Chrome A Lite by Evercoat. Its very creamy and smooth and is less prone to air bubbles than other brands. I used it on my Benz front fenders 30 years ago and it hasnt cracked or bubbled yet.

On the filter flow washer the inner tub is able to wobble around and bang into the outer tub during spin cycles. At least that’s what would happen on my parents machine. Over the years this caused several small holes my dad plugged by drilling them out, then installing a bolt with a rubber washer. It isn’t pretty, but it works, it’s fast, and when finished it won’t be seen. So unless your goal is restoration it may work for you.

Depending on the size of hole, I've had good luck with filling small to medium gaps using plain old JB Weld.

Earlier this summer I went though this exercise with a leaky Filter Flo. After all rust has been cleaned/prepped fill the hole/gap with JB Weld, and once dry, sand it down to the desired contour of the surface and finish with your favorite coating. I've been using POR-15 for several years now. It will flake off non etched porcelain surfaces, but those that are rusty it will stick for a good amount of time. Once I'm done with the cans of POR-15 that are in stock my plan is to shift to a marine epoxy.
