HomeMade Fan Shroud

Pretty slick work there, but seeing it on that pretty, yellow, painted hood makes me cringe.
THX, it is wood and placed VERY carefully. To our Canadian neighbor I apologize for the "get it in the USA" comment re plywood. I don't know if Canada has plywood producers and if they do I AM SURE the quality is the same as south of the longest non-secured border in the world. I was referring to asian plywood which although may be made of exotic hardwoods ( teak/mahog' ) is NOT layed up with quality adhesive !
Moisture is THE key. All surfaces and especially end-grains MUST be sealed with at least one heavy coat of epoxy resin. If only one coat, do not sand.
