I just finished putting in a new trunk and need to put some sealer in between the trunk panels and inner wheel houses. It looks like the factory used a seam sealer of some kind. Any suggestions on what I should use? Where can I find it? Thanks!

for in the trunk you can use 3m seam sealer in a calk type tube.lay down a bead,get a small acid brush,dip it in laquer thinner then brush it till it looks good.for any seams outside the car i would recommend the two part seam sealers,a little pricer because you need the special 2-tube gun.i used the regular type on the seams under my rear window and the bottom quarter to rocker seams and now it's starting to crack(5 years later)http://members.spree.com/entertainment/ochrisl/

3m "Fast and Firm" sealer can be found at most auto paint suppliers, or order it from "The Paddock". Other parts dealers may also carry it.

actually it would be easier on yourself to use a "brushable" seam sealer inside the trunk areas. These sealers are designed to be applied w/ the aforementioned acid brush and are a much smoother consistency to allow to be brushed w/out having to use the lacquer thinner, or some other form of flowing a thicker sealer. These can be found at auto parts stores, but more often found at a paint and body supply store.

As for the two parts sealers on the exteriors...they will crack as well...probably sooner. Because they are catalyzed, they set up much harder, thus making them more brittle. I do however prefer the flowable 2 part seam sealers for drip rail applications....they flow out very smooth w/out tooling and make a much neater job than using your finger to smooth out other types of sealers in that application.
For the other exterior seams....an ordinary automotive joint and seam sealer in a caulk tube (Fast and Firm as previously mentioned) will work fine for these areas and remain flexible for a long time.

I like brushable seam sealer - available from your local body shop/auto paint supplier, JC Whitney, and Eastwood http://www.chevelles.com/forum/biggrin.gif http://www.chevelles.com/forum/biggrin.gif

Make it look the way you like it, forget what the other guys say! :D

only problem with the brushable type is after you brush out a few feet it usually turns into a clumpy mess.thats why i like to use the kind in a tube and laquer thinner.it makes it look much neater.

Try 3-M ultra pro, it's a little better than the 3-M Fast n Firm.
The fast n firm is a little less goopier, but sometimes it tends to crack after a while.
