Is there other sorts of hand sanders other than the 3 easi shoe sizes and those half sheet orange block sanders. I also use gib ones but why isnt there a long board about 100mm wide! And whats you secret to super straight panels, apart fom guide coats, as we all know they can leave huge hollows, or hours of blocking and checking. Im sure I seen on Overhaulin or American Hotrod a guy using what looked like a long bit of 6x1 once.

I make my own sanding blocks out of high density foam, they can be any size I want. I have a half sheet sized one that I glue 36or 80 grit onto with aerosol contact adhesive. If you want to go old school straight, the secret is to block your filler coat with 180 or even 150 grit wet and reprime it to fill the scratches after that with a thinner coat of a good primer surfacer. Edit: I also have a longboard about 600 mm by 100 mm made from MDF which I glue sandpaper onto.

Buy new panels, cheaper then spending hours reworking used ones and filling them with poo

A bit hard to source the XY Falcon ones nowadays, it's also not economical to chop and weld a rear quarter that can be repaired on a newer vehicle.

Just glue sparingly so you can change the sandpaper when it wears out.
No doors or rear quarters on that site, at $1000 per guard you would still repair the old ones if they weren't too bad.

Back in the day we used a long sand paper file with 150 grit, on filler coats, primed over that and blocked the primer with shorter cork blocks. We had some pretty good results that way. This was in the days of pink spray putty that sanded like chalk.

lmao.DearSpares. Been burnt by them in the past. You still have to get the old guard removed and new one fitted, prepared and painted. Not really worth it for smaller dents and scrapes. But new floor pans and such that have the cancer.chop it

I made a sanding 'block' that's about 600 long too. I made it out of steel and welded handles to it. I made clamps at the ends. I used to use it for up to about 120 grit. Its heavy work but gets panels straight fast.

Its all in the way youuse it. Sand horizontallyverticallyand diagonally asthe panel allows. Big long strokes and ride off the panel at the end. I have done cars that were 100% ripple free and only ever used half sheet blocks.

Dura-Block do a 6/7 block kit mate. Has a couple of longer ones in it.
But.Google fairing boards and make ya own. We use to have some cool ones we made when doing super yacht stuff.

Why 800! You're just making more work for yourself.
The only time i use 800 is when i want to "flow-coat" a perfect clear job.
99% of the time i only ever use 400, but i may on a special occasion use 600.
If you're having problems laying metallics over 400 i think ya may be over-reducing ya colours.

works on anything. the cars I have done included a xf ute, hq ute and landau coupe. Big flat panels need time and know how. There isnt a magic tool that can make up for lack of that.

Hey gun', just bite the bullet and buy this kit mate.
Nothing wrong with a bit of 4 x 2 x whatever length you desire.

Piece of perspex the desired length, chamfer (sp!) the edges slightly. 2 tennis balls with 1/3 cut off, fill with bog and attach to 'board'. We found tennis balls were a good shape to fit in ya hands and they don't get sore.
Just a suggestion, rather than pee around with glue for the sandpaper, make the block 115mm wide and as long as you like. Glue wide velco hook material ( get it from a dressmakers supplies) to the block,then use the new 3M hookit roll sandpaper available in 115 and 70 mm and grades from 40grit to 400.

Clamps waste sandpaper, the velcro suggestion has my name on it.
