Landy corrosion

Hi Everyone.
I'm about to set about the body work on my landy and the body panels have some corrosion Does anyone know of a treatment i can use before i put the etch primer on?

I used some hammerite acid stuff - can't remember its name but it was reaaly good. Have a look on their web site.

am fighting ally corrosion at the mo on the series 2 restoration , especialy near steel to ally joints bolts etc, even loose fixings will cause earth problems leading to elec galv corosion. the ally should be polished clean with a sander etc then aluminium acid brushed on and washed off , that wil get shut of the white fluffy stuff, then dry up and spray with the acid etch primer, as a wash prime, spray over with acid etch everytime a jobs done , so as to be sure of full coverage, paint wint stick to ally if youve missed a bit

Thanks for the info. Ill give it a go before it turns to dust and blows away.

At work we use 'alodine' to treat aluminium before etch priming.
