Re: My recent fabric job

That is Stewart system equivalent of dope, not paint....makes me want to shy away from anything Stewart system now if it cant handle auto gas...back to polytone it is...

poly tone wont handle it either. it won't come off but it will stain badly. I only use airtech anymore.

Re: My recent fabric job

I've seen car gas loosen Polyfiber too.....if you think it wont happen, you're just kidding yourself. There's some nasty stuff in it!! As far as alcohol, that's about the least nasty stuff in there! Worst part is that it varies from refinery to refinery, so you can't fix it all. I do know that I've had plenty of Stewart's with 100LL on the inside and outside and haven't had any problems with it....

Hi Dave
Was the EkoBond, EkoFill and EkoPoly all damaged by the autofuel? After using Poly Fiber for years and years I had decided to use Stewarts for my current covering project. After seeing your pictures I'm going to start over with the Poly fiber.
I hope there is some way to salvage your cover job!

Re: My recent fabric job

How long had that paint been on Dave? I've seen car gas do that, but usually on semi-fresh paint. We used to topcoat the inside of the fuel tank bays (no matter what system) to guard against this.

About 1.5 years. Their manual has no mention of this hazard. I never had to worry about this with Randolph dope.

Not possible to top coat the fabric inside of an Aeronca wing tank bay.

They claim that avgas will not do this I they they are wrong, it will do the same, the green glue has been softened too, yuk.

This process was a waste of my efforts.

I searched the manual - no mention of this hazard.

Rob

that is the least of my problems

They say it only happens is the gas gets on the inside.

Hmm I wonder where overfill gas on a wing tank goes or leaky gas/wing tank or fuel near a quick drain goes?

Do you think it will touch the inside? I think so.

The glue, the fill and the topcoat are all eaten up.

Re: My recent fabric job

Gas seeped out overnight, about .7 gal , I had a weepy fitting. Autogas- non alcohol.

Hmm, what a mess. Stewarts says you can expect this with autogas.

Kinda wish they stated that up front in the STC.

Very very unhappy.
