Most of my IC, Metho/Petrol or Kero powered models where there is a posibility of spillage I coat with 30 min. Epoxy diluted somewhat with Metho for easy brush application, few thinner coats does a great protection to ply-wood boxes or even Depron foam I use in turbine powered models. Acetone or Metho Spirit is a great cleaning agent I use on my hands, immediately washed with Solvo or soap agents after.

Well protected wooden engine mount box with numerous coats of thinned down Epoxy, after 10 years of operation. Now convert, to E-power! LOL.

Now silent and cleaner.

Turbine powered foamy fuel tank sump well protected with Epoxy coating, finished off with few coats of paint for 'estetiks'.
