Ive got just enough left over to do the doors and boot lid. 5ltrs??? You been drinking it? I used 1.75ltr of cavity wax and 2 litres of waxoyl underseal.
That's the plan as mine is under shelter it will be done as last thing you will want is water getting stuck in there no matter how much treatment is in there to prevent rust etc.I'm sure you'll both know this but for others reading I thought I'd add that when doing doors and bootlids after a few days clear out the drainage holes as they will most likely be sealed with wax/cavity sealant
It's grim smelling stuff have had mine done for three weeks + and it still smells when I get it back will have the windows open for a few weeks to try and shift the smell!Hadnt thought of that actually Phil. Top tip
The smell of dinitrol is unmaskable tho. Ive got 3 magic trees in there and it still over powers
