John Tidbury Posted October 25, 2020 Share Posted October 25, 2020 I am building a petrol powered model using real wood!. What do I do to protect the firewall etc from any stray fuel that gets blown about within the cowl or fuel tank bay. I would like to know before I close any access to these surfaces. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted October 25, 2020 Share Posted October 25, 2020 I used epoxy resin (laminating resin) painted all around the engine and tank bays the same as I did for glow motors. Quote Link to comment Share on other sites More sharing options...
John Tidbury Posted October 25, 2020 Author Share Posted October 25, 2020 Thank you Bob. I hadn't thought of epoxy resin (I was dubious about the normal glow treatments of varnish etc), so it sounds the ideal solution. Quote Link to comment Share on other sites More sharing options...

Matt Carlton Posted October 25, 2020 Share Posted October 25, 2020 +1 for laminating epoxy. If I don't have that, normal epoxy resin glue works if slightly warmed and spread with a cut down credit card or similar. I tend to try to do as much as possible before assembly so those tricky corners are covered, and before engine mounts etc are attached. Use a cotton bud or similar to make sure you protect inside and holes for control cables, mounting bolts etc. It's also worth arranging a little drain hole in the tank bay in case of a burst tank.

John Tidbury Posted October 26, 2020 Author Share Posted October 26, 2020 Thank you everyone - I was sure I would get good advice and I am not disappointed. I think this thread should be closed now Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted October 26, 2020 Share Posted October 26, 2020 Use a thin slow setting variety of epoxy to allow it to penetrate into the wood . I have seen quick set epoxy used in the past that peels off and once lifted traps oil etc that then soaks into the wood and along the grain .
