Fan repair

There are two large exhaust fans in the trailer.  They have a fairing that is hidden behind a nice fabric vent cover.  This fairing acts like a venturi to make the fan more efficient.

Unfortunately, the plastic was cracked and damaged.  First we thought it would be best just to replace the fans.  But, they are larger than normal  - 18"x18" - and the RV supply stores only have 14"x14" fans. 

So, we decided we'd just repair the ones we have.

I used masking tape as a base for the filler.

Ready for some fiberglass!

It doesn't have to be pretty - it won't be seen.  But, the cracks and missing plastic have to be fixed.

Several layers of fiberglass cloth and resin.

Trimmed off the excess.

And here it is - a trial fit - looking up thru the trailer roof to the hangar roof.   Just a little more trimming and it will be ready to install - cost - almost nothing since we had the fiberglass leftover from some boat project!
