Herculiner over Rust Bullet ?'s

[Chase77]

A while back I read someplace that when applying Herculiner or Durabak over a newly Por'd or Bulleted surface, you'll get the best adhesion by allowing the Por/Bullet to setup until its a little tacky then spray on the Herc/Durabak (rather than sanding down the surface 3 days later to provide the needed grip between the 2 materials). Is this correct or do I really need to wait 72 hrs then sand it all down?

Thanks,

Chase

I POR'ed my floor of my tub. Waited about 24 hrs and used a wire bush on it. All you want to do is roughen up the surface a little. I think if you waited the por may be to hard to scuff. I then Durabak'ed the hole interior of the tub floor and up the walls about 8". That was 4 years ago. I have had no problems. Nothing peeling or rust returning. Make sure you pull all the bolts out your going to want to use later. I also did under my fuel tank cause it was really rusty.
I would not recommend herculiner. I also have a F350 that I durabak'ed the bed in. About the same time a friend of mine did his truck with Herculiner. His sucked. It started peeling almost days after.

Bullet and Herculiner

I did the entire tub on my FJ55 with RustBullet, followed by Herculiner. The only place it scuffed was where I gouged the floor with the rear seat bracket. When I finished installing the seat, I just hit it with a little more Herc. I didnt really do any prep on the Bullet other than the Scotchbrite pad the Herc came with. Im gonna put down carpet, once I get the water leaks fixed, so the Herc is good enough for me. Hope that helps. Hodag

Im goin to to spray it when the BUllet is tacky and see what I come up with. Buddy of mine did the same thing to the underside of his fenders and they came out pretty nice. Illl post up pics and a review once I see how it all turn out. Thanks again.

Im doing my tub this weekend with Herculiner (only 59.99 after rebate right now!) If interested, I can post what I think of the Herc if it helps.
