chassis painting

[niallyc]

Hi All,

I have a question that might seem a little dumb but I', going to ask it anyway and hope for the best!

Should I prime my chassis as I go or should I wait till its all finished and do the whole lot? I have just tacked all the bottom rails together and I am concerned that the cleaned surfaces will start to rust. With this (possibly irrational) fear in mind, I began degreasing, sanding and degreasing again. I'm using a u-pol weld through primer on the joints and an acid 8 etch primer elsewhere.

Are my fears of the dreaded oxidisation fairy unfounded? I realise that I'll probably have to clean off the joints again when I want to fully weld them up so there will be a bit of extra work.

Any help on this would be appreciated. I have to go and get some fresh air now! DO NOT paint in the garage with the door closed!
