Default rear hatch drain mod???

I thought I saw a little kit in one of my catalogs but I can't find it.

Something about drilling a hole and installing a little hose to keep water out of the passage between the glass hatch and car free of water???

If you do a search in this or C4 general you will find that the concensus is that, while it may work, the possibility of causing harm to the body panel far out weighs any gain. The gas filler drain modification is another story!

:cheers:

There is a kit. I ordered one from Mid America a few years ago but could not bring myself to drill holes in the car. It's still in the garage somewhere.

The best hatch drain mod is a turkey baster :lol:

Actually I use a large syringe with a long plastic tip but the turkey baster works just fine also.

No way I would drill 2 holes in my Vette for something a 99 cent turkey baster and 42 seconds takes care of just fine.......

I have been thinking about doing this, and wonder why no one else has. cant we just fill that area in with a little sealent to keep the water out?

I think this is a good mod. The hatch area holds water at the front corners. I've never had an inside leak, but the water draining down the sides of the car makes a mess. The drain holes are inconspicuous and easy to make.

The kit from MidAmerica has good instructions. Just follow them. You can eyeball the hole placement near the inside corner. The exact spot is not critical, so near the corner is good enough. I would add two things: 1) use duct tape to cover the paint of the hoop so the drill chuck does not scratch it. 2) use silicone cement to secure the grommets. After the grommets are in place, close the hatch and use a pencil to wedge the grommets down until the silicone is dry.

Only maintenance is a pipe cleaner once a year to make sure the tube is clear.

I use BLUE painters long tape to tape the seams of the hatch before I wash it. It comes right off after being wet and the channel stays dry. no harm to paint at all. :seeya

Don't do it! Drilling will only cause problems down the road when the seal leaks. Just take the time to remove the water as others have said, use a turkey baster.

Did this before I got car painted, easy to do. I bent the edges of the grommit to fit the "V" groove it goes in. I used a small amout of 2 part universal body adhesive, solid as a rock

I've got one on my work bench. Been there about 13mos. Something keeps coming up :mad

If you do a search of the archives you won't find 1 derogatory remark from someone that has it installed.

All warnings of disaster come from someone who doesn't have it.

I use the bulb baster. Got one for about 50 cents somewhere and it drains every drop. Takes about 10 seconds on each side.

Really???

I installed them 10 years ago to this day I still have not had a problem. Every Great once in a while they get clogged, but nothing a piece of wire won't cure.

I say go for it, if you are afraid to drill the holes, I will do it for you vvv90 :D

Until now! IF you decide to do it...be DOUBLE damn sure the drain hose goes through BOTH layers of fiberglass!!! You'd be AMAZED at how much water will drain into your rear storage compartments if one of the tubes goes BETWEEN the panels! :eek:
