Seam Sealer Questions

Planning the order of things for priming and sealing. Trying to avoid having to sand/scuff anything after shooting epoxy, so I will have 5 days to get things done. For the underside, I will epoxy prime, seam seal, then probably epoxy over seam sealer and then Raptor liner. For the floor pan and interior seams I will epoxy primer then seam seal. Do most people just leave the seam seal as the final item and then carpet over or do more epoxy or a finish coat over the seam sealer?

One thing I was thinking about doing is to just shoot epoxy "stripes" where seam sealer will go, then seam seal, then a full coat of epoxy over everything. This way i can take my time seam sealing and just have to scuff the small strip areas.

I would just "pencil line" epoxy everywhere you're going to seam seal, seal it with epoxy after seam seal, and then bed liner so if you don't get to it right away you can just scuff the small areas before seam seal as you said in your second option. You don't have to do a top coat over the epoxy if you aren't going to have any wear and tear to an area. I would put down some sound deadener on the top side of the floor pan to protect it though.

Thanks for the second opinion. More I think about it the narrow pencil lines are the way to go so I can take my time on the 400 gallons of seam sealer that need to go in.

Any area where you're going to use seam sealer should get two coats of epoxy primer. So, just shoot the whole area with one coat of epoxy, apply the seam sealer, then shoot the second coat of epoxy. I did this on my Mach 1 project and it worked great.

After applying two coats of epoxy to the underside of the car, I would call it good. Think hard about the raptor liner. It's extra cost, extra hassle and won't give you any more protection than epoxy primer. If you ever go to sell the car, potential buyers will wonder what you're hiding under the bed liner. Of course, if you just really want to shoot bed liner under the car, by all means, do so. It's your car.

Currently working on a 1970 Mach 1 project. See it here: http://forums.vintage-mustang.com/vi...ode-build.html

Good points. I may wait until I can take 5 days off and do it all at once. As for bed liner, still deciding on underside. Will for sure do it in wheel wells and trunk. Never selling this car and I have 1000's (literally) of photos to appease a buyer that I'm not covering up anything if it ever came to that.....
