Beware condensation - Page 2

What's the solution Ken? Is there a way of stopping it forming - or perhaps draining it?

There is no way of draining it as the bonnet covers all angles and directions it would not be possible. Stopping it in the first place seems to be the best option to me.

Since finding it two days ago I have tried two things with the weather being the same both nights.

1/ left it off = no condensation

2/ put back on = condensation

This proves its the warmth from the insulation making the underside warm while the night time temps makes the top of the bonnet cold. This confirms its the insulation causing it. At least it does to me but I am no expert in condensation. At the moment I have not tried anything to cure it but my thinking is something like a flexible underseal which will take the stresses of the bonnet opening and closing.

Eventually I am thinking of putting on a sealer and then putting back the insulation. The sealer will seal the underside paintwork against any condensation that does form but once the cold metal is covered it should not form condensation anyway. I will try different things and will get back.

Ok Ken - look forward to hearing how you get on.

Mine seems to be condensing too. The engine side of the insulation has tell-tale white marks around the washer jets.

Its worth taking a look Simon if only to put your mind at rest. The fasteners just pop out with a wide bladed screwdriver. Only take a couple off to check as thats all it needs. If its wet take it off and dry out the insulation overnight. Its only a 5 minute job to put it back on.

The condensation is probably nothing to worry about to be honest but its one of those things that if I know its there I have to cure it :lol: or at least try

I'm not sure if the spray wouldn't attack the fibre in the insulation board. I have two white areas on mine but I put that down to the washer jets leaking slightly after my travails with them. I'll have a look later today when I go and see her.

Its not fibres on mine its a thick foam type stuff. If a sealant is inert it would not be a problem but finding an inert one could prove difficult.

Anyway gives me something to do :lol:

Wouild a light spray of Waxoyl with a bit extra in the frame on the bonnet underside help? If nothing else it will repel the moisture and stop it creeping. Perhaps a light spray in the foam with hot Waxoyl would be a good idea too, it may soak in and and form a barrier on the surface, meaning the water will have nowhere to go except evaporate or run out down the sides and front, and being inert it shouldn't harm the foam either. That does mean of course a bit more Waxoyl around the inner wings and slam panel though to keep the damp moving.

Very good idea Pete I will follow it up this coming week.

Nicely done
