Another tank sloshing thread

[Xengineguy]

Hi Jeff, my vote would be a product called Red Coat, I have had very good results with it . It is mek based,remains pliable (unlike cream)
Your biggest problem is getting ALL the cream out! Some people say mek dissolves cream, I never got that lucky! In the last 20 years I have used red coat on maybe 400 /500 tanks.

Thanks, their website says available at O'Reilly's. Your success means a lot. I really want to avoid future problems and the track record of Kreem leaves me uneasy. BTW, another name that came up was Hirsch. Also BTW, the two-part Caswell website says something like "most failures are because of improper mixing". Maybe so. I gather Red Kote is not two-part.

You are correct Red Coat is not two part. Clean up and thinning done with MEK.
Normally you won't need to thin it. Make sure the tank is completely dry before coating. Cream = PITA. Good luck. Mike

Red Kote says specifically in their spec sheet - "Do not use Red-Kote on
fiber-glass or any plastic".

I would bet they are worried about the MEK softening the resin in the glass tanks. Don't know. Test it, and see if it works for your application. Mike

I decided a while ago that if I ever have problems with my fuel tanks I am going to make new tanks out of aluminum,..but rather then weld the seams..I will use a fuel tank seam sealer and roll the seams,..a pliable sealer,..doing this should eliminate any vibration/torque induced cracks that can occur at welded seams

Why do you seal a aluminium tank?

I have the 6 gal aluminium wingtanks in a Kitfox III, there is nothing slosh inside and it works.

Mike, or anyone, Has anyone used Red Coat with ethanol gas? I am thinking about returning two cans to O'Reillys because the label warns do not use methanol. It says some have experienced the methanol dissolving the red dye and sending it through the engine. Should I care if red dye goes through my engine? I usually don't use gas with ethanol, but Rotax allows 10% and I have in the past.

I assume this is done to the old style tanks not the tanks with the SS7?

Mine are aluminum, from the early 1990s. I suspect my leak was through the gasket for the fuel gauge, which is a float geared to a dial reader. But previous slosh had started flaking.

I called Red-Kote support to answer my own question. They said Ethanol is OK, Methanol is not OK. Auto racers sometimes use Methanol.
