David Davis Posted March 5, 2017 Share Posted March 5, 2017 Has anyone ever used Hamerite on a model aircraft? If so do you think it would resist 10% nitro glow fuel? Quote Link to comment Share on other sites More sharing options...
Plummet Posted March 5, 2017 Share Posted March 5, 2017 No comment re fuel proofing - but a word of warning in the case of the formulation of Hammerite is still as it was. Read the tin carefully. When it gives time for recoating believe them. If I remember correctly, they say something like "recoat before 24 hours or after a month" I got caught with this. If you cannot recoat quickly enough the paint comes up in cracks and craters like a miniature lunar landscape. Plummet Quote Link to comment Share on other sites More sharing options...

Hammered enamal hence hammerite. Quote Link to comment Share on other sites More sharing options...

Hammered enamal hence hammerite. No, no, no, There is a huge difference between a smooth hammerite finish that looks blodgey (and rather nice, in my opinion) and a surface that will grate skin (that I got.) I was using 'smooth yellow hammerite' on a car bodyshell. It looked far from pristine! Plummet Quote Link to comment Share on other sites More sharing options...
edgar Posted March 6, 2017 Share Posted March 6, 2017 I used the smooth version of Hammerstein on a cowl, the paint was a few years old when I used it, it looked ok at first but it wasn't fuel proof to 10% nitro. I don't know if this was due to the age of the paint or just that it's not fuel resistant but I won't try it again. I hope this helps.

Denis Watkins Posted March 6, 2017 Share Posted March 6, 2017 Not an answer to your question David But Hamerite's claim to fame was to resist weather, and this was achieved by painting it on Super thick; instructed to lay it on This goes against all our lightweight requirements Whatever paint I use on cowls, I allow this to dry, 2 days at least, and a week if I have time then airbrush on 2 thin coats of standard fuel proofer (Balsa Cabin) Quote Link to comment Share on other sites More sharing options...
Martin McIntosh Posted March 9, 2017 Share Posted March 9, 2017 I sprayed my Precedent Stampe with Hammerite Smooth blue and silver, also my Mustang with silver which goes on a treat. The blue, however, gave problems, possibly due to a second coat going on too late. I fuel proofed with ordinary skinning/moulding epoxy, eventually settling for brushing this on the wings and most of the rest other than the cowl.

stu knowles Posted March 9, 2017 Share Posted March 9, 2017 I wouldn't use Hammerite on a model, too heavy. I have tried it on a classic car chassis and found that 'ordinary' paint lasted better than H'. My personal preference is car cellulose or Solarlac using Clearcoat as a fuel proofer over either one Quote Link to comment Share on other sites More sharing options...
Dwain Dibley. Posted March 10, 2017 Share Posted March 10, 2017 Hi D.D. Hammerite is for van wheels Matey, not loverly models........Like on my one... D.D. Quote Link to comment Share on other sites More sharing options...
David Davis Posted March 10, 2017 Author Share Posted March 10, 2017 I only wanted to use it on the aluminium cowling of my "Baron 1914," a very popular trainer here in France which looks vaguely like a Fokker Eindekker. Given the small size of the cowling, weight gain would not be an issue and I was mainly concerned about whether this paint was fuel-proof enough to withstand 10% nitro fuel.I suppose the simplest thing would be to leave it in the natural aluminium. I have used Hamerite on the wheels and underside of my 1974 Rover Dwain. Quote Link to comment Share on other sites More sharing options...
Dwain Dibley. Posted March 10, 2017 Share Posted March 10, 2017 A Sweet motor D.D. We used to have a P5. more rust than car LOL I have refurbished several ford 100E's in my time, 1172CC side valve, 3 speed saloons. got no room now, too many models. D.D.

Martin McIntosh Posted March 10, 2017 Share Posted March 10, 2017 This is all Hammerite finished. Looks fine to me and not at all heavy at only 6.2kg. Clearkote is highly unlikely to withstand 10% nitro. Even the epoxy finish has now suffered a little where the exhaust sprays the u/c; 5% nitro.

Tim Flyer Posted March 10, 2017 Share Posted March 10, 2017 Good post David! I was also tempted to use hammerite smooth white on my recently built Wot 4 kit. Reasoning was that cellulose car paint doesn't seem to be easily available in cans and I don't want to spray. ( I used Dulux undercoat in the end and coated it with Spectra polyurethane. ) . If I had used smooth hammerite I could have used my 2 pack Klear Kote fuel proofer that is properly fuel proof. (I use epoxy as fuel proofer inside the model). It's still a pain for me painting models and fuel proofing. Doesn't seem to have improved since I started in the 1970s. Ps that's s lovely finish Martin!

David Davis Posted May 9, 2017 Author Share Posted May 9, 2017 A few months ago I borrowed a set of car ramps from a friend.They were rather rusty so I painted them with black Hammerite. I was passing her house today so popped in, squirted some model aeroplane fuel (10% nitro) onto a rag and rubbed it vigorously over the ramp. There was no staining on the rag. That's good enough for me. Hammerite is fuel proof if you give it enough time to harden off! . Quote Link to comment Share on other sites More sharing options...
Peter Christy Posted May 9, 2017 Share Posted May 9, 2017 I used smooth Hammerite on an old AcroWot undercarriage to replace the (much too solid!) original one on my SpaceWalker. The two are visually identical, but the AcroWot one is a lot more suitable for our field! The Hammerite red is an almost exact match for the red on the SpaceWalker! The engine is mounted at an angle, so that the exhaust exits between the u/c legs. So far, it has proven remarkably resilient to hot glow fuel! The only proviso I would add is that the engine is a Super-Tigre, so straight fuel, no nitro. -- Pete Quote Link to comment Share on other sites More sharing options...
Tim Flyer Posted May 12, 2017 Share Posted May 12, 2017 This could be my painting pain finished for ever. I hate painting and hate the sticky mess made when nitro fuel starts eating the paint. Klear Kote fuel proofer is no good on oil based non celulose paint so I was stuck with using polyurethane varnish to fuel proof which I found a poor substitute. Coating with clear epoxy doesn't work well on the outside as it darkens gradually when exposed to light and I find often has a bumpy pinholed surface. It's going to be brush on hammerite for me next time!! Quote Link to comment Share on other sites More sharing options...
David Davis Posted May 12, 2017 Author Share Posted May 12, 2017 As I started this thread I suppose it's incumbent on me to put my research to the test! I'll paint the cowling of my Baron 1914 in black Hammerite and observe the result. Watch this space! Quote Link to comment Share on other sites More sharing options...
