The body seams are in K-36 prime, but I want to put on one more coat. I'm thinking now is the best time to apply the seam sealer, just before the final prime. How do I smooth out the sealer?
Also, the top of the dash is now in DP prime, and I have to apply seam sealer at the welded seams judt before the W/S pillars. Can I apply it now and spray my flat black over it or should a coat of K-36 go over the sealer?
Thanks,
Rich

What kind of seam sealer is it? Some are sandable and some are not. Usually if it is dry you can sand it and recoat it without any problems.

I don't see anything on the label that indicates that it is sandable. It says, very flexible, smooth with water (a wet finger?) can paint in 30 minutes.
Does this help to describe it? Mfgr. name is Auto Tech, I got it from my body supply shop.
Thanks,

You could probably sand it with a smooth paper like 320 or 400 grit. I use Fusor 801, it stays flexible ,and can be painted shortly after applied. Some of the seam sealers, must be sanded after they sit for a period of time. I guess they must lose their chemical adhesion. I think it is a good idea to let it sit, and sand it with something fine. I think that will work out,and it will look nice if it is sanded.

Auto tech, they offer some good products, I use to use them all the time.
I loved the seam sealer but I don't remember it being water borne.

Anyway, if it says "smooth with water" on your finger is exactly what that means.

You really need to practice a little to get the hang of it. This is it in a nutshell. You mask off where you want to put it just like as if you were painting it.

Let's say you are doing the rocker to quarter seam. If you run tape on either side of the seam right on the roll of the seam as it comes out flat on the quarter and the rocker. The exposed area of the seam will only be about 3/16" or so, just the "crack" down the middle of the seam. You then run the sealer down the crack with pressure forcing it in. You then wet your finger with water if it is water borne or wax and grease remover if it isn't water borne. Just get your finger wet and run it down the seam pushing in again with pressure. This will smooth it real nice. Right now, untape it, don't let it dry. There will be a little edge on the seam sealer, you can wet your finger again and smooth out that as well.

That is all there is to it. :D

Best to smooth it out is with a little laquar thinner and an acid brush while it's still wet.

Hey, thanks everyone for the detailed responses!
