I've been kicking around the idea of herculining my rocker panels for a while now to cover lower door dents and scrapes/gouges. I'm wondering if this would be a good rust preventative? I'm moving back to Wisconsin early next year and would like to do all I can to keep the truck free of cancer.

 

I would say yes--as long as the surface it is covering is completely rust free and the backside of the surface is rust free as well. If that is the case, then go for it. Oh, don't forget the UV Topcoat if you go with black! I made the mistake of not using the topcoat and paid the price dearly; my herculiner job is totally faded in places from the sun.

 

I'd say no given past experiences with other self-applied liner products.

 

A lot of us have had excellent luck with Herculiner specifically though, especially on painted surfaces with proper prep work (sand, prime, roll on). As far as completely sealing out water goes, Herculiner, like paint, does an excellent job when applied properly.

The fading thing is another story with the root cause being operator error.

Why do you feel Herculiner will not seal off moisture properly?

 

where do you get herculiner

 

I got mine at Checker Auto. I ordered by UV Topcoat from ebay.

 

Checkers has a rebate on it right now. $20 off if I am remembering right.

 

I have had hucuiner in my bed for 3 years now and it is great, I would highly recomend it, I am going to do the same thing to my rocker panels

 

DANGIT!!! Everytime I finally get the idea of Herc-ing my rockers out of my head, someone starts a thread about it! One of these days I'm going to break down and do it... Or not... Or I will... Or I won't...

 

In the situation you mentioned above, it's the paint that's keeping moisture out of the metal, not the herc, IMHO. IMHO, the only solid way to prevent rus is with a very well done prep/etc/sealer-primer/top coat... That's after having done powder coating, spray in bedliners, Por-15, roll-on liners, etc. Most of those, once scratched, will allow moisture to wick underneath and keep it trapped there.

Just my opinion... Hope I'm wrong.

 

I LOVE the herculiner on the bottom of my truck. Just be sure that you spend lots of time on prep work or it will not stick right! Yes, this does involve scuffing the paint that it will be covering up. I have had the Herculiner on my truck for about 3 years now and it is a huge help in keeping the rocks from chipping up my paint now that i have BFGs that like to throw rocks. I would totally recommend it as long as you do it right, otherwise dont bother doing it because i would imagine that stuff is hell to remove.
