Second coat done. Hammerite is largely slated for being no good these days (volotile compound rulings no doubt) so I am going to be interested to see how this holds up. Especially the flat areas I have painted it on. Job done and I know at least for this winter pipe protected. The areas I did with the silver Hammerite along the sills on surface rust still looks fine. (Should do after only 3 months)

I think they key might be to gloop it on, no thin light coats but thick water resistive ones, it dries shiny so water beads and rolls off from what I have seen so far.

One less thing of concern for now. =D>

If the Hammerite is good I can get the vehicle up in the future and sort out any other issues I see under there. But for now to the eye it looks nice a tidy under Bongo. I feel I have sealed off everything I can practically do with the vehicle on the ground for the winter.

Now ready for a few 250 mile autumnal round trips and possibly a trip to Wales on top of that.

Just a couple of update additions/findings... to the heater pipe situation checks. Earlier as I am sure I bored everyone to death :lol: I sorted my underneath exposed heater pipe (light sanding, kurust/hammerite/smear Waxoyl.) the drivers side one. A few weeks back I saw that same pipe under the bonnet, you need to look down at about 45 degrees left side of the bay (from how you are looking at the vehicle) and you will see it following under the bulkhead, fairly low down. I noted some surface rust so this one I suggest, a light sanding, awkward but possible with a bit of wet and dry in hand, and smear with Waxoyl as the access is a nightmare even with a free hand and no coat/jumper sleeves. I simply sprayed some waxoyl onto my hand in a latex glove and smeared it all over as best as I could. It would be worth checking your own pipe at this point as it seems vulnerable to rust here. It is a bit awkward to get to but you can do so with a few scratches to your hand and forearm :? , probably worth smearing every 3 months or so through winter months.

Also under the passenger seat you can find the other heater pipe, that has also got surface rust so this morning I did some light sanding and the same process, Kurust and then I will Hammerite it this afternoon. Just thought it might be of interest as I did not know the pipes were accessible from these places.

this pipe is affected badly with the windscreen drain dripping on to the pipe usually where it joins the last rubber pipe to the front heater, it may be advisable to lengthen the drain so it falls to the floor instead of the pipe.

I wondered why it would start to rust there it is hardly in an obviously exposed area.

A little update, I checked this today whilst tinkering with the 5 way resistor for front blower and saw that the Waxoyl is not really staying on the rear heater pipe section that is visible from the bonnet.

So plan B is that I have smeared a thin coat of temperature stable silicon based grease. Hopefully this will have better staying power than the Waxoyl when the pipe heats up. Obvious now when you think about it that Waxoyl would warm up and probably run to the lowest point it can and or drip off on a long journey.
