Friends,

I have a bit of a problem. I misapplied the epoxy when trying to fuel proof the engine compartment. I wasn't paying attention and didn't mix enough harder with the epoxy. As a result, the glue is still wet and sticky a week later.

I was thinking about cleaning it off with an alcohol mix and applying fuel proof paint instead.

Am I taking the right approach?

Thanks,

DB

That's just about all you can do. Clean it off and try again.

How close were you to 50/50 and did you thin with rubbing alcohol ?
If you haven't started to wipe off the mess yet, use your heat gun to help kick off the hardener. When heat is applied, the epoxy will start to flow again and then will set up much quicker. I've done this many times to get the epoxy to flow into every joint and crack.

Ditto, apply heat, and keep it in a warm place (The warmer the better) and it should harden up

What I have done with sticky epoxy (probably not mixed well) is to mix another batch with just a tad extra hardener and paint over top of the first coat. Works every time but may add extra weight.

Hi All,

Thanks so much for the suggestions. I followed Ken's advice and removed the epoxy with rubbing alcohol and water. It worked like a charm and I was able to reapply epoxy with the correct hardening mix. HuskerBoy, I took your advice and applied heat to get all of the cracks. I'm really happy with the results.

Everything looks great. The fuelproofing is done and I've mounted the engine. I'm now hooking up the servos.

Thanks again for your expert advice.
