The part in the red circle bolts through the underside of the body and requires a seal between it and the body. The stuff that was in there looked like a liquid rubber or silicon of some sort. What do you use?

I think it is some sort of sealant to prevent water splashing up getting into your boot... A sort of chewing gum that stays soft...

About the only thing not to use is silicon sealant unless it is neutral cure - ie doesn't rely on the evaporation of acetic acid to cure. As the acetic acid will get trapped and cause corrosion.

You can use pretty much anything else that won't rot, from string doused in stockholm tar, thro bitumen non setting caulk, to urethanes, however adhesive urethanes like sikaflex and auto windscreen adhesives are probably a no go as they are too strong - you'ld never get the plate back out in the future.

I think the easiest thing to use is self adhesive closed cell foam insulation strip - the thin stuff about 1/4" wide and 1/8" thick used for sealing around doors (in your home) to prevent drafts just stick it on the plate and push it in. No worrying about getting sealant allover the wheel well as you fumble about trying to insert the coilover from below with one hand and reach into the hatch with other hand to try and line up the studs and get a nut on one of them.

I used 3M body caulk strips.

Me too .. and you can use that in a few other places too, like the rear flange of the front guards to the body. Seems very similar to the original material.

Dave, where did you get it from? I looked and couldn't find an Aussie source.

Mrmerlin

body shop supply store sells 3M dont know about Aussie though ,
also good for resealing the blower box

Tom in Austin

Yep, I used leftover string caulk from re-sealing my airbox. Double-bead, plenty of room on top to run it around ...

Jon, thanks for that.

I always knew using (most) silicone sealants on body parts almost always creates or speeds up rusting and corrosion in the area used...but I never knew exactly why until your post. I always thought it was because silicone trapped moisture so effectively it retained any moisture against the metal parts causing them to rust/corrode prematurely.

Learn something new every day!

Thanks again,

You can smell the acetic acid (vinegar) in curing silicone sealants. Pungent.

This looks like the 3M stuff:

Seems to be available here.

Thanks to all!

Marty-

I've used DAP weatherstrip caulk that you can buy at Home Depot. Roll out a strip in your warms hands to whatever size you want. May be more conveneint than looking for an autobody supply place with the 3M StripCaulk product. Also-- NAPA stores usually carry th 3M or their own M-S brand of same.

Hilton ... I think it was a body shop supply wholesaler here in Tas. I'll look for the invoice and post here where I got it.

O'Reilly (Checker) supposedly carries it locally. I'm gonna check it out tonight.

Thanks for the alternative.
