Seam Sealing The Interior

posted Jan 18, 2013, 7:36 PM by Jonathan Imberi
We had another day with a high in the upper 30's so I decided to seam seal the interior. I knew it be best to apply the seam sealer in the afternoon when it was warmest, so I started this morning by prepping all the areas for seam sealer. I wasn't sure how much seam sealing I would be able to do with what I had left (about half a can), so I decided to focus first on the seam behind the rear seat backs and the two seams for the lower firewall.




I started the prepping by using steel wool to scuff up the surface of the POR-15 so the seam sealer would have something to grab onto. All it really does is dull the gloss finish of the POR-15.


Then I used the air compressor to blow out all of the seams.


By the time Sara came home for lunch I had finished prepping the seams. A box came in the mail from Fine Lines and it is huge. If I ever need to ship Sara somewhere I have a box that will work. (Some air holes and a travel pillow and she would be all set.)


Back to work. The first thing I seam sealed was the seam behind the rear seat backs. 


Then I moved on to the two seams on the driver's side of the lower firewall.


Then I did the two seams on the passenger side of the lower firewall. When I finished with this side I realized I had a lot more seam sealer left than I thought I would. I forgot how easy this stuff is to work with and how well it spreads out. I was able to leave the seams fairly thick and yet still had plenty left over. I decided to work on the other areas of the car where we had removed the original seam sealer.


First I prepped these areas the same way I did the other seams this morning. (I did not take any pictures of this part.) I seam sealed the driver's side rear shock mount and along the wheel well.


Then I seam sealed the passenger side rear shock mount and along the wheel well.


I went over the seams on the passenger side rear storage area.


Then I painted seam sealer over the drain plugs. I started with the two above the fuel tank thinking it would help with any fumes and to make sure they are completely sealed.



I also did the driver's side rear storage area.


I followed this up and met where I had stopped on the driver's side wheel well.


I sealed the seam running across the trunk and decided since I had plenty of seam sealer left that I would seal all the drain plugs the same way I did the two on the rear deck.

I still have a little less than 1/4 can left of seam sealer. I should have enough to touch up any spots I missed. Smells normally do not bother me much, but the seam sealer fumes are quite strong (especially in a closed garage). I probably could have found more to seam seal this afternoon, but I had enough of the smell by the time I finished the last drain plug.
