I would still just cut it with the 40 and finish with the 80. I never took strictly 40 to completely strip to total bare metal and don't recommend doing so. I used 40 to, as I stated, cut it down to where you see metal but some final layer primer is present. Then finish stripping with 80.

Okay. I understand what you mean. I may go this method. Unless I can find a decent price on media blasting in my area.
But I am so far leaning towards your method.
Thanks for the advice!

Appreciate it!

Hey Chief,
Do you know if the clean strip discs are any good or as abrasive as the 40 grit?

Roughly with a DA, how much hours and discs/paper would I be looking at for doing the full size 66?

Never tried discs. Might clog up easy, might create too much heat, might do both. You would have to give it a try and see what happens.

The clean strip disks are the bomb, but they are expensive and don't last as long as I would like. I wouldn't linger too long on areas of bare metal after they take the paint off. They don't produce much heat at all, but they are pretty course. I love using them, hate buying them.
But ... I've never had the opportunity to use them on outside sheet metal, I've only used them on firewalls, floors etc.

Clean strip discs work excellent. I have them for my Angle grinder and a box of small ones for my Angle die grinder. They dont clog easily at all and dont build heat unless you stick to a small spot for a long time, they also leave the surface clean with no grinding Mark's
Use long sweeping motions and you get almost zero heat buildup. I stripped my entire car with them and it was way faster then my D/A could have done. I used 3m brand I think first then switched to some cheaper ones I found on Amazon for half the price, I think the cheaper ones lasted longer!

I'll be getting familiar with them again shortly, have to strip a bunch of 15 year old POR 15 off a firewall.

Another nice thing about them is they will tear through bondo very quickly.

Which ones did you use off of amazon?
Around how many did you need to strip the entire car?

That will not be fun. Sure to be worse than when I had to remove trunk spatter paint from an engine compartment and that was a bitch.

For the large flat surfaces I would use paint stripper. D super remover from CTC has worked good for me. The contours and edges basting works well without the fear of distorting the metal. There is a blaster in your area call Finish Line Nia. that will just blast, or continue to epoxy prime and will do a complete paint . Not cheap but reliable nice work.

Brand was Duropeak. I bought a 6 pack I think for the angle grinder, used them all. The Dow grinder ones I think I used 5 or 6 for under hood, door jambs ect.
