Finally got the roof and visor welded on and welds ground down..... I do have the paint on the roof .... factory dodge I presume since it is off of a dodge caravan... there are a few small cracks in this paint... can I sand those down or does the whole roof need to be down to metal?? and if so is there a stipper I can use since sanding this paint is hell... is stinks very bad I am wearing a dust mask. if I have to take it down to metal can I use a stripper and if so do you have to do anything to nuetralize the stripper once the paint is off or does it dry and is rendered useless? I was going to start to go over the welded area with some evercoat but I didn't want to start with out finding out about the paint on the roof...

thanks,
simon
