"A long board air sander is good option but it seems to me that
www.flexicat-tools.com has much longer tools especially for two people.

Do you thing it is possilbe to get any 70" long board?"

You can check out a marine supply shop for the larger sizes, 3M does make much larger sizes.

for 70" you could laminate 2,3,4 layers of 1/8" particle board and fit handles as you need.

Even on large boats the curves keep changing, 70" would be completely impractical for finish work. Much easier to make matching blocks for each area from hard Styrofoam foundation insulation boards from a building supply store.

A piece of thick conveyor belt makes a handy sanding block and can be cut to most any dimension..cheap too, usually from the scraps in a belt shop.

I have a set of durablocks, but they're not flexible. I bought 24" K block, it's flexible and looks like a quality tool. I'll be using it on long quarter panels, hoods, etc. For the price it's best deal imo

I have had a set of AFS Blocks for about 4 ior 5 Years now, and have actually wore our one set and replaced them-I like the Stainless Rods that can be taken out for more flexibility, the Stainless base plates that actually work, and I have to say that the owner of AFS is also a Body Shop kinda guy, and is always open to suggestions and ways to better his product-recently, I needed a new 6" block, and he sent me three when I only ordered one-one of them had Leather on it (for holding the PSA Block paper), and he asked me to let him know how it worked-I like it the best-I bought a set for my Brother-in-Law who is restoring a '67 Mustang, and he loves his set-he had previously worked and worked on the bottom of his front Fender and couldn't get it straight, he had it straight within 15 minutes after he got his set. I like that every time I order something from AFS he sends a "surprise"-I love the guy.

I haven't yet found a panel that I can't get flat with them, and they are comfortable for these old, tired hands-expensive? Yeah, a little, but they work-

New To Bodywork

Reply for 'New in Body Work': Soft Foam - Hard Foam - Flexiable tools might be handy for smoothing or getting into difficult areas; but that's it! I am a retired twenty year veteran of auto body finishing and found that in order to achieve flat straight and true reflections in the paint finish as well as hold to the original contour of the panels, is to use a long hard board especially in the initial leveling of the body fillers and in final stages of sanding out the sand scratches in the primers surfaces. Starting with a air board and moving onto a long hard board in a cross-hatch method this is the best way to level and stay with the original contours of the panels (even Fords from the forties). It takes a little time to learn the technique but worth it in the end. Don't worry - stop sanding when you see metal and it's also a good idea to use a guide coat so you can see lows that you can't see or feel.

Blocks Oh Blocks!

Blocks are only as good as the person thats using the tool. Yes, find yourself a nice flat piece of oak. and cut em in any size you want. This will give you the flattest surface possible in the beginning stages. As mentioned above. I have used all sorts of home made blocks and barely ever had to buy anyones Hi dollar piece of foam. This works very well also in the cutting process in wetsanding your clear. Use the longest board possible for the panel your using. Method as mentioned is important as well. Without a doubt, use guide coat, I prefer the dust powder guide coat over the spray can ones. You want a panel flat, the harder the better. Be creative. Psa long board sandpaper on a roll can fit just about anything.

Yes, using long hard board on clear coat is the quickest way you are going to cut orange peel down or level irregularities. It takes a little nerve, but once a person gets good at it they never go back. We also, liked using the powder guide coat. I agreed often self-made tools are the best answer - the last few years we were in business we specialized in XKE Jags and found a need to designed a adjustable long 'hard' board that we used on all our customer's restorations, one of the cars received 99.99 & Best Paint in a concourse show. We spent the money and got a patent on the idea. Now I am trying to find a way to get this concept on the market, I think a lot of guys would find it very useful, it just works.

Your welcome. I have one of those, I use others, and a lot of homemade ones that fit what i'm doing.

Have too agree with the homemade flat blocks as well. Make mine out of different thickness and lenghts of plexiglass. Will always make what you are sanding dead flat, because the blocks are dead flat. Try blocking a 52 caddy rear quarter with durablocks, just aint going to happen. Also use with the first cut of the clear to acheive the laquer like clarity.

There is a plastics business nearby that I get all the peices I need, they cut them to length right there. I think the last time I was there they cut up several shapes and thickness for around 15 bucks. I don't know where you are but if you look into any companies that specialize in plastics they should be able to help you out. I find the plexi works real well in various situations. I have one that is about 1/16 thick 2 3/4 wide by about 8 inches long and stays perfectly flat to whatever you bend it around to block something curved. Then for blocking round inside curves I use different sizes of pvc pipe.

Plexiglass, good idea - bends and stays flat . By the way, in a previous post I think someone mentioned wrapping paint sticks with sandpaper, we used this idea and it helps in certain situations. I was to the recent Sema Trade Show in Vegas and I see that 3m is getting smarter, they applied their Hookit facing material to paint sticks & put together a little detail kit - with paper cut to fit the paint stick......
