I've owned my 1974 LH SL/R since 1998 when i bought it as a completely factory original six cylinder auto. Since then i've replaced the running gear with a EFI 355, TH350 & 9" diff. I've run it twice at WSID with a best time of 11.9@113mph on it's third pass. As much as i loved the car the way it was, the factory paint had deteriorated badly & surface rust was appearing in places, so with words of encouragement from a couple of good friends i decided to give the old girl a new coat of paint. This is how the car looked until today.

Starting about 11am today, my good friend Scott & i proceded to strip the car. I was wrapped upon taking the rear screen out to find not a spot of rust.
Posted Image
Posted Image
My luck ran out once the front screen came out.
Posted Image
Posted Image
Oh well, just get into it. Masking the car in preparation for the paint stripper.
Posted Image
Posted Image
My mate Scott has painted a few cars for me, we work good together. He works cheap too.
Posted Image
The basic body on my car is pretty good, first coat of stripper revealed no suspect repairs or bog.
Posted Image
Scott getting into it. A messy shite of a job but had to be done.
Posted Image
By 5pm, most of the factory paint was gone from the rear of the car & roof turret.

This is far as we went today, tommorow the doors, guards etc will be coming off to be stripped out & sent off for media blasting & the door apertures will paint stripped. Hopefully by this time tomorrow, the basic shell will be in epoxy urethane primer.

My aim is to have this car painted & finished by christmas.

Hey Matt

I was wondering how long you could leave the old girl before you gave her a lick of paint.

Why didn't you keep your old thread going it would be good for all the members unaware of your build so far?

What colour you going for ? I am sure it will come up looking the goods going off the missus's car , How is the little lady's Torrie going?

Can't wait to watch the step by step lessons again on how to panel beat the correct way.

The car will be painted back to original Sable silver with the SL/R black stripes & paintouts. I took plenty of photos, tracings & measurements so i can replicate them as close as possible. The interior is stripped out & will be retrimmed as original in Ash grey with Herringbone cloth inserts. Basicly i want to restore the car back to how it would've looked when it was new right down to the 3300 badges on the guards even though it has a 355 V8 in it now.

Here are some more pics of the car for those who don't know the car as i was too lazy to revive the old thread Posted Image

Today was fairly productive, we didn't get any epoxy primer on but then we didn't get to work until 11am & we only worked until 5pm. Still i'm happy with the progress. I began by stripping off the front sheet metal & n/s doors so Scott could start paint stripping the apertures. The Sydney Morning Herald came in handy again.
Posted Image
Posted Image
While Scott was busy with the paint stripper, i went to work on the o/s/r quarter. It was basicly straight, but had plenty of minor high spots & park dents. I started by blocking the panel with P180 to "pick up" the inperfections.
Posted Image
Next step was to start dressing down the highs with gentle hammer & dolly work, & bringing up the lows with a slapper & dolly. The areas i couldn't get to with the dolly, my trusty dent puller was put to use. After running a body file over the panel i gave it a guide coat then blocked it with P120.
Posted Image
This picked up any areas that weren't right & any small dents i missed. A couple hours more work & i was satisfied with my work.
Posted Image
Posted Image
My aim is to metal finish this car so no body filler will be used, instead epoxy urethane primer will be applied followed by polyester spray filler.
Posted Image
N/S door aperture & sill are bare metal, not a spot of rust & only minor dents on the sill.
Posted Image
Posted Image
Next step is to repair the rust in the front screen aperture. I didn't bring the tools i need to do this from work so i'll be doing this during the week & hopefully moving onto repairing the n/s/r quarter & roof turret next weekend.

Not much progress this weekend, got pounded at work so i was tired saturday, didn't really do much & pulled the pin early. Got to work at 11.30am today & went hard till 4.00pm so this is what i got done. First up, rust repairs. I started by making a channel from an off cut of steel at work.
Posted Image
There were about 5 or 6 areas that needed plating, both lower corners & along the base.
Posted Image
Posted Image
Posted Image
I started on the right side & began working my way along to the left. First step, cut a section from my pre-made channel to cover the rusted corner & scribe the outline onto the aperture.
Posted Image
Posted Image
Then i cut the rusted section off carefully using a cut off wheel & air hacksaw. I'm butt welding all the repairs & metal finishing them so i won't have to use bog to "hide" the repairs so everything has to line up perfectly. Here, the aperture is ready for the repair section to be welded in. The blue paint is zinc weld thru primer, i plug weld the repair section here as i don't have a spot welder.
Posted Image
I tack weld the corners then slowly & paitently weld the section in, finishing with an air grinder, belt sander for the tight confined areas, then an air sander. I got about half the aperture done. The line between where i joined the rust repair & the panel directly below is where i had to sand away the factory lead wiped join. I can fill this with polyester filler.

This is what i have left to complete the rust repairs.

When i got sick of grinding & welding, i worked on the rhs rear quarter, i've got it 80% finished so far.
Posted Image
Posted Image
While i was working on the rust repairs & rear quarter, my mate was finishing off the lhs door aperture removing all trace of the original paint & sealer from the rain gutters & body joins so we can address any minor rust that might be forming. So far so good, the body shell is exceptionaly clean & rust free confirming my faith in older drivers. The original 85 yo owner of this car took very good care of it.

Posted Image
Next step is to finish the rust repairs & lhs quarter, then move onto repairing the beaver panel. Tomorrow the front panels will be going to get media blasted followed by the doors. I've already re-skinned both passenger doors with NOS skins, the rhf door maybe getting re-skinned too as it has rust near the belt mould & i have a NOS skin if i need it.
