Hey Fusion!I ve been building chameleon enclosures for about 13 years,first i use a 120 grind sand paper and sand the all cage to perfection.2nd i like to add a nice color to my wood,i apply 1 or 2 coats of stain depending on the color,i use a WATERBASED stain(Saman waterbased wood stain)its none toxic to chameleons and its easy to use.3rd to protected my wood,i apply 3 coats of a EXTERIOR WATERBASED CLEAR(Varathane outdoor crystal clear water borne diamond wood finish)with IPN(interpenetrating polymer network technology)this crystal clear finish is designed to provide maximum protection against the sun,water,weather and chemical damages.If you want a super nice finish just slightly sand by hand with a 220 grind sand paper between each coats of clear to remove all the inperfections.......I hope my grammar is o.k,english is my second laguage.
