When to Blast
Posted by: DragNut

So I have my MGB on the rotisserie and its stripped down and ready for the metal work that needs to be done...floors and sills, I was wondering if its better to blast first and prime before starting the metal work? Im thinking the blasting would show other spots that might need repair....? Any suggestions?

Definitely blast it first so you know what you are dealing with

Agree. And have it epoxy primered too. Way easier to work on a clean body she'll than constantly be cleaning before each task. And the e-primer will keep surface rust from forming.

Also look for one of the guys that uses water and ground glass. They are also portable and don't leave the residue that soda does. They have featured it on My Classic Car.

I support all the former posts...

My limited (and all ready filthy) garage couldn't handle either the bead blaster or the epoxy painting... so I loaded the body and rotissorie on trailer (sans end pieces) and hauled to blaster... reassembled then on to paint shop for epoxy coat the same way.

Unless your blaster(or you) have a lift, it's most nigh impossible to get to all the bottom parts while lying on your back! All I needed was a flat trailer, a buddy, and a portable engine hoist.

The epoxy coat is critical as every resto I've ever seen, seems to take far longer than the original plan and this solves the "garage/fingerprint issue".

Who ever does it... make sure they really know what they are doing! Earlier media blasting of my 35 MG was too abrasive and too much pressure... and excessive heat warped two of the 4 bonnet pannels.Big bummer!

You've got the right plan... good luck and post some pics?
Cheers

Some blasting companies can spray metalized metal in the area's that have rust pin holes. You can shape this metal by filing or sanding to get the shape you want. Agree, you should prime the body after you blast to prevent surface rust. Take your car with rotisserie and put it on a flat bed trailer. Then take it to a blasting shop after you have ask questions on how they blast and treat the panels in the primer process. This will save time in the restoring process and labor you will need to do. The cost will out weight the labor trying to do it yourself.

I had this company spray metalized metal on the floor boards and in the outer rear boot area of this GT. It had the normal rust that had a lot of pin holes. They treated the rust area's first before spraying the metalized metal. Then used epoxy primer that works with PPG base/clear paints. In the ends saved lots of time and cost not replacing panels.

Good luck with your build!

So I was talking with Rick from R&S Blasting and its $165. per hour...he thinks its a 4 to 5 hour job....he also recommended cutting all the rusted metal away before he blasts...now I have to replace both floors and both sills..is it wise to cuts all of that away first? I was concerned about the body sagging with all that missing . My plan was to replace each sill one at a time.

May be money & aggravation ahead of the game to start with one of these.

I'm not familiar with the term "metalized metal". Does that material/process involve zinc? Once metalized metal has been applied, are there issues with welding? (Toxic vapors?)

Excellent thread, I hope to start restoring my C GT soon. But have been putting it off after restoring the body on my V8 the old school way of using a sand blaster and cutting/replacing panels.
The old school way works well, but it makes one heck of a mess and really chews up the hours!

You mean the trim on the cowl vent? You just pry it up. Might want to spray the pins first.
