Not something that's easy to track down using the search function!

Next step for me really is painting the chassis. A quick scan of the 'fact sheet' for POR15, which I had intended to use, suggests that it shouldn't be applied in cold temperatures (which is what we're likely to have until about April or possibly May next year....)....


Anyone got experience of this? Should I just find other jobs to see me through the winter?

Can you heat the garage for a few days to make sure the ambient temp is OK and to dry out any moisture?

You can rent a space heater for a day for not a lot of money from most tool hire places, they are noisy but will heat a garage up very quickly, most run on kerosene or diesel. POR 15 from memory cures using moisture so as long as its warm being damp should only help it go off quicker.

HTH

My 'garage' is actually an air-raid shelter which is half buried in the ground - so I expect it will be difficult to bring up to a decent temp - although I haven't tried. Was also somewhat worried about inadvertantly gassing myself somehow...

As long as the air temp is raised the surface temp of the building shouldn't matter, I run mine in a damp old workshop all day with no issues.

Had you considered epoxy mastic 121. Have a look at rust.co.uk as they have some advice on painting on cold/damp garages.

I painted my chassis with Por15 in my mates non insulated shed in winter. I made a bit of a tent around the chassis out of plastic sheeting and had a heater in there.
Years later and the chassis/por15 is as good as when I applied it. It is good tough stuff. I used the grey chassis coat then top coated with the chassis coat black stuff.

I will say though, use a proper decent mask as even with a good vapour mask on, I was floating a little bit so take fresh air breaks!

Also, take your time to methodically work your way around each tube as it is easy to miss bits....but the Por15 high I was on could have contributed to that!
