Tim240z Posted November 20, 2001 Share Posted November 20, 2001 I have just coated my interior with Hammerite. I have used this before on my Land Rover chassis and it is as tough as 'ol boots' once it has cured (to the point of annoyance if you need to weld on it later), so I am very happy with it's effectiveness on rusty surfaces and it's strength and longevity. I was wondering if anyone has used both and has a comparison. I hessitate to use POR because I have no experience with it (stick with what I KNOW works), and hammerite is more readily available (Home Despot etc). Any opinions?

pparaska Posted November 20, 2001 Share Posted November 20, 2001 Tim, I haven't used Hammerite, but I have used POR-15 and Hirsch's "miracle paint". Both are moisture cured urethanes. I'm wondering if Hammerite is also? Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 20, 2001 Share Posted November 20, 2001 I used Hammerite under the paint thats under the battery box. It turned out pretty good, and yeah the stuff is durable. I havnt used Por 15 but have only heard good things about it, in particular how good it coats and how little you end up using. I'm pretty sure they do the same sort of job, inhibiting the rust by basically starving it from nice moist air. Por 15 might be more economical if your doing under the car or large sections. *Shrug* Regards, Lone Quote Link to comment Share on other sites More sharing options...
Tim240z Posted November 20, 2001 Author Share Posted November 20, 2001 Pete, Hammerite claims that as the coating cures, millions of fibers interlock to create an impervious barrier. Once that stuff cures, the only way to remove it (for welding etc) is to use a grinder!!!! They use this stuff on ocean oil rigs and platforms Tim Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 21, 2001 Share Posted November 21, 2001 I used por on my entire car and it works great. When it cures it is extremely tough to get off of any surface. A small amount goes a long way. Brush it on and you would never know it. I would recommend it to anyone. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted November 21, 2001 Share Posted November 21, 2001 Being in restoration I have used most of all things out there. The POR ( or similar products ( has it place. You should know that it contains isocynates which are extremely poisonous. You shouold not spray POR with a fresh air system. regular charcoal filters do not filter out isos. because it uses isos, it is a very hard material. I like the silver paints better than the black . They contain more solids are are used under black etc. I have good experience topcoating POR type( I keep saying it this way as I use another product ) with epoxy primers which is the best out there in the auto refinishing business. I let the POR tack up and then coat with epoxy. Now I use hammered paints also. I use these on hardware etc and am quite happy with the results. It is not a cured product so chemically is nothing like POR type paints. It does boast an interlinl, and yes it is quite durable. For spraying in your interior, it is a good choice if that look is what you want. If anyone has any refinishing questions, painting tec, send them my way. I am new to the Z car scene, but have much experience with Mustangs and general body painting/ engine building/mechanical areas. Quote Link to comment Share on other sites More sharing options...
