Brushable seam sealer
« on: November 04, 2011, 05:54:59 am »
Does anybody have any tips on applying brushable seam sealer? I bought some to do the repairs I made to my cab and wanted to do the neatest job I can on them. I tied a small area with an acid brush. It smooths out good with the brush but putting it on with it is messy. I was thinking of trying a cake decorating baggie to make it apply similar to a caulking tube. Any other ideas?

I also used an acid brush and then I smooth it out with my finger.

I cut the corner off a zip-lock baggie and used that to apply some sealer. Kind of like the cake decorating baggie idea that I had. It worked pretty good. Much easier apply a small amount right were you need it. Then I used the acid brush to smooth it out some.

Here is a pic of the area that I tried.

I just wanted to add this after using this on the bottom of my cab. I used 3M brand and the smell is very strong and lingers for a long time. You have to have some ventilation with this stuff. One day later when I walked by my cab I could still smell it flashing off. It is good stuff though and worked well.

I did all my welds and the factory seams with it.

If you dip the acid brush in laquer thinner it smooths it out.

At work I use 3m heavy bodied seam sealer which is a 2 part epoxy based that builds well and dries in 30k min and is sandable but requires a $60 duramix gun but works really good 3m also males some seam sealer that can comes in a caulking tube I use masking tape to tape off the seams so the lines are nice and straight

It is good stuff though and worked well.
Sorry I overlooked this before...Kinda coming in at the end like "closing the gate after the cows get out."
 I've not used any of 3M's seam sealer in many years (maybe they have improved some of it), but over the years in the bodyshop business I've found it to be pretty much the worst stuff available. Most dried too hard & would crack along the seams, fall off, ect.
 Hopefully, they have re-formulated that over the time & it won't give you trouble.
 The best sealer I've found is made by Kent & is not available at stores to my knowledge however a bodyshop may sell it to you.
 Other good sealers that should be readily obtainable are the Urethane Tan colored stuff made by Fusor & is available in a regular caulking tube, the Gray Wurth stuff or the Gray stuff made by U-Pol & can be used in a regular gun with an adapter. I can get you part numbers if you would like. Interesting that you have probably never heard of any of these companies, Huh?
 I would strongly suggest looking into one of these before you work on the top side of your truck. Not to bash 3M as a whole, they do have some good products, but to be honest...I don't use near as many as most people would think. Lorne
