Thanks for the tip. I know Eastwood IIRC has a weldable primer. I have a dehumidifier running on constant on in my shop. I was looking for something that would allow me to spray and them only have to remove what I needed to do the work on. But now that I think about it there is little point to doing it that way as I don't want the pitted rusted metal left around at all. At this point I'm hoping to get it in the shop the weekend after thanksgiving. We are taking a cruise from Jacksonville to Key west and Nassau that ends Thanksgiving morning and I have the rest of the week off. I just hope to get a few sunny days to push it outside nad sandblast the engine compartment out. Probably to ambitious an undertaking in that time frame. But I'm going to try!-- Mark Price markprice242ATadelphia.net Morgantown, WV ---- mail@xxxxxxxxxxxx wrote: > Mark, I'd just use a cheap spray bomb paint to protect the area from > rust temporarily.
