A spot of therapeutic DAing tonight. Done all down the driver's side, then realised I didn't have any etch primer in the cupboard, ah! well.

What grade of discs you using?

Just my 2p worth. I tend to start the process off by using a knotted wire brush on the grinder. I think I then use 120 grit on my DA generally and then a bit finer to give a lighter keyed finish. Etch primer is a wonderful thing

However, before I etch prime I give the bare metalwork a light wipe with Kurust poured onto a soft cloth.

This combination has never let me down yet with regards to ease of stripping and final finish. See the 1300FWD resto thread for example.

Start:

Finish (nearly):

I'm not sure Andy, the same as I used last year,

I'll let you know.

I've always thought those knotted wire brushes look a bit harsh Ken, but obviously they do the job ok. My prep work doesn't have to be that good Ken. Just enough to get my sprayer around to see what he's let himself in for.

He will go over it again anyway.

Must admit I would have tended to agree with you Marrtin, that is until Howard brought his green 1500 round and we tackled the front valance. The results were great (IMHO), and it was much less aggressive than I had anticipated. If anything it gives a finish that is a little too polished, hence the finishing with a light DA'ing. Try it, you might be pleasantly surprised.

I tend to go a bit OTT because that's just me and I do my own paint stuff anyhow. I'd love to get a pro in though

It's always a good thing to share tips and so on.

Both routes look like they give a great finish. Even better if theres not too much filler work to be done

Excellent progress Mart, I'm looking forward to following this!

Hi Mad Mart, is the interior of your donor shell (the blue interior )in good condition and are you putting it back in the finished sprint? or would you like it to go to a really good home in an early 1850 that I own, if your thinking of selling the seats and carpets could you send me a message. many thanks matt

I will do Matt.

Having been held up on the other project I thought I'd give Mary a hand with PUS today.

Most of the body is back to bare metal now but the rear passenger-side door looked a bit iffy. As I started to remove the filler, it became apparent that there was quite a lot of it...

...in fact it was about ½" thick in places...

...so I got a hammer & wood chisel & managed to get most of it off in lumps...

then I finished it off with my new knotted wire wheel. I've been converted Ken.

...

...as you can see, there is a fair old dent. It looks like the person who repaired this didn't even try to push the panel out at all...

Anyone got a picture of these said mythical tools I have been hearing so much good talk about?????

@ Glenn:

@ the resto thread:
It never ceases to amaze me that people will use that much cataloy when it would have been so much easier to pop the door out with a hairdryer & freezer spray in the first place, a technique that, even on a compound curve like there, usually allows the job to be finished with the very slightest skim of lead. Still, they must have been good bodgers 'cos the earlier pictures didn't even suggest the extent of that depression.

At least it'll be done properly now though.

Glad to hear that you have been converted Mart. They are pretty handy things and save a huge amount of time and effort.

Purplebargeken · #74 Post by **Purplebargeken** » Thu Mar 10, 2011 8:42 pm

So Mart are you going to tell how much of a difference the knotted wire wheel made then?

That brings the list of the converted up to about 10
