Fuel Proofing

[arun 0]

Hi All,

 

Am at that point in the build of my Magnatilla when I need to think about fuel proofing the front end of the fuselage. What do you all typically use for this task and how much of the fuselage should be coated (I'm erring toward the entire liteply structure if you know the Mag)?

 

I've heard some versions of Ronseal are perfectly good fuel-proofers. Can anyone elaborate as if I can pick it up from Homebase will be much better as I have little chance of getting near a model shop this weekend and don't want to wait for mail order if possible.

 

Cheers.

Hi Arun.

 

Ronseal is OK, anything to seal the wood really.

I use Spektrum paints who also do a matt, satin and clear aerosol fuel proofer.

You can also get tins of the stuff old fashioned style that you can just slap on.

 

You can always do it later to be honest, so I wouldnt worry if you need to order it. All the parts of the Maggy can be got at without the cowl/motor/tank so you can do it after covering and before final assembly if you wanted.

I use epoxy resin thinned with meths; I have some remaining from a fibreglass project. I find it flows into all the cracks and soaks into the wood nicely. Alternatively, Ronseal varnish (the exterior solvent based polyurethane kind not the quick drying water based kind) is okay or you can get various specialised fuel proofers like Solarfilm Clearcoat which are quite expensive for the small tin you get.

 

You should coat anywhere there is bare wood that fuel might get to. Definitely all round the engine and fuel tank compartments and on the fuselage where fuel or oil might flow e.g. wing seats.

Thanks chaps, sounds like I can delay until just prior to covering which won't hold up my build at this point. Thanks for the various brands/tips I'll take a look into them. Cheers.

I use Aerocote, I buy the Matt and don't shake it if I want gloss!!

 

This is two part mix(with catalyst), and I use it AFTER covering to help seal the covering edges of all seams as well as the engine and tank bays.
