I got told that the magnetic signs can cause your bodywork to start to rust .a few guys I know around area where I live told me .where are they based nathen
Dont know about the rusting part, but ive used magnetic signs for past 2 yrs and no signs of rust where theyve been yet.
Not sure where there based, i did it all thru their website signs4vans.co.uk. i uploaded my design and photos to be used. They send a couple of designs back, maybe slightly different to what youve designed. Just to give you a couple of different options. You then comfirm which one you want and in my case, by end of the week i had them sent out and received.
Before this company i used smaller magnetic signs from vista and didnt have any problems with rust either. I suppose it depends how good the bodywork is on van. Put the signs on when dry and it shouldnt be a problem.
