Rim,
Welcome to the board. This is one great bunch of folks and I think you'll get a lot out of it.
I will put in the obligatory plug for Zero Rust for all those areas that need to be sealed up and won't be getting any further treatments. Go to
www.zerorust.com for product information.
For the balance of your question, there is a bulletin board at
www.autobodystore.com that is excellent for us DIYers. Ask anything and some really skilled individuals (Pro's and DIYer) will do their level best to get an answer or several, depending on how many ways there might be to do a job...... With input from the board, you can approach your local paint jobber with a more ammunition. Jobbers can tend to sell you what they have, more than prescribe what you need.... Just saying......
I think some of the members have used Len's board and will chime in.
Cheers
Bruce Palmer
