I did another metal shaping course a few months ago and he had a HQ in there and asked us all to check out the bonnet which was in primer. Looked fine to all of us, nice and straight. Then he walked over lightly pushed on it to show us it oil canning on the outer flat sections..... from blasting. It had lost its tension and had been brought to him by the owner to try and get it fixed. Big job and a lot of skill needed to shrink it back and keep it flat.
No matter what gear is being used, to remove paint you either have to hit it hard or for a long time so for me if you are hitting it hard enough or long enough to remove the paint then it's too much risk.

You haven't sand blasted yourself then. As I said large flat pans I would sand. Underneath a V6 bonnet I'd do no issue. Sanding creates more heat than blasting. Sand blasting creates the perfect key for fresh paint as well. Older cars have thick steel. I don't know who blasted the HQ but obviously was out to make money and went to quick. My blaster throws more cool air than sand so it's cooling as it goes but still quicker than any other method.

Not arguing bud you've helped me lots. It's just a low and slow approach I take. Well and truly understand the wasted cars from sandblasting nightmares. I know of a Perana ruined because of it and so many others. It's large flat panels that don't take well to hard and fast blasting. Though I think the bonnet bulge on a V6 would stop the issue that the HQ experienced.

This is Maddie's car. As you can see sand blasted and rust free. We do the large panels by hand. Home job no paint on these pics just cleaned metal. Roof and outside panels done by disks. And the plate. It has no rust really at 50 yr old

One thing about sandblasting is the grit gets everywhere, in rails, gaps that don't exist.. my last car went on the rotisserie and was slowly turned and hoovered for a few hrs, when I was done I done it all again, the stuff just keeps coming out, air compressor helps heaps to flush it out as you go

True about grit. I plug the holes and tape them to minimise but it goes everywhere. Easy to clean out but takes time. Also warping panels can have slot to do with grit size pressure and patience. I just used washed sand and recycle it 4 to 5 times untill it's powder.

My brother's plan is to have it sand blasted at a later stage prior to painting, the outer body. This will remove tempary etch primer, surface rust dad left behind, mic states to roughin up the panel is good.
He has alot of experience and knowlage when it comes painting.

Bonnet and roof are easily done by sanding rest of it is sand blast. Never both sides of same panel ( that though is when it's done quickly by huge machine blasters).

Paint within wheel arches were always mat black on every make and model Ive ever seen, and I believe "factory".
However, many owners who do 100% full-on restos and "rotisserie" bare metal resprays desire to
show their hard work adorned by "same-colour" 100% everywhere underneath as well as inside.

Hi Maddi
Jumped on line to see if there's been any more progress to your car?
Please show if so.
For me, nothing seems to be taking place,
Thankful tho he managed to put his hand in his pocket to buy all the materials needed to prepare and paint.
