Default Is epoxy fuel proof?

Well the title pretty much says it all. Do i need to buy the fuel dope stuff or will epoxy do just fine?

Thanks

Yes it is. What do you want to fuelproof ? There are also other options

Use finishing epoxy if you have it. You could use slow cure epoxy too - some prefer to add 1-2 drops of denatured alcohol to reduce its viscosity. If you add too much, it may not cure well and turn rubbery.

I don't think anything is truly fuel proof except metal and some plastics. By that I mean if you put any of the so-called paints or glues in a bottle of fuel, they would break down.

But epoxy is fuel proof for a long time, so unless you drench the engine compartment with raw fuel and it sits there, then you won't have any problems with it.

Fuel proof and exhaust proof aren't the same thing, btw. Fuel proof means raw fuel proof. A lot of things that can hold up to the oily exhaust break down to raw fuel.

Most epoxys are fuel resistant, not fuel proof. Best to check
with the manufactor.

Steal, from the nearest available women, a little bit of nail polish remover and mix it in with your epoxy.... This will thin it out and allow you to use a cheap brush and "paint" it on wherever you need it!

Nail polish remover is acetone based... Go to the nearest drugstore and buy a bottle of acetone... because it is very usefull for a number of things: cleaning epoxy off brushes (works like a charm), thinning epoxy (only with slow curing types, otherwise the acetone gets trapped in the cured epoxy and then it takes weeks to cure), degreasing things before you glue them (very effective), cleaning your planes (but first make sure your finish is acetone proof!), adding it to your fuel (1-2% as ignition improver), ...

I would not use acetone for most of the applications mentioned. Not only is it expensive, but it's a bigger health hazard. Use denatured alcohol for thinning epoxy, degreasing, and diluted soap water for cleaning planes

5-minute epoxy is not fuel proof. 15-minute epoxy is somewhat fuel proof. 30-minute or 2-hour epoxy is fuel proof.
