Guys........hey I am finishing a 64 Impala and was wondering? I usually use 1000 FF then 1200 and 1500 then 3000 trizact but I am out of 1200.

I forgot to get it from Len and my local supplier is out also. How far will it throw me or would I be OK with going to 1000 to 1500 then 3000 and leaving out th 1200 step????


Thanks

and cross cut, then just take a little longer on your 1500, follow with a good effort with your 3000 and you should be fine. I would suggest doing a panel start to finish to be sure your system is working before you cut the whole car and find out there's a problem or that you need to go back to the 1500/3000 steps.

Soaking paper overnight makes it a whole lot better.

Cool thanks for the input. I am using the dry finishing film for the car. I love the way the sanding leavs a guide coat.

The same rules apply with Finishing Film, cut a little longer with the 1500 then finish with your Trizact.

I'd suggest you stay with your dry system up to 1500 then switch to wet. 1500 Trizact wet leaves no pigtails and will cut the others pretty much out. One thing I noticed with the 1500 though was that it seems to have little pins of abrasive that stick up and cut into the paint sort of slicing rather than cutting. The effect - this is my own observation only - is that the sanding scratches came back after the buff and polish, for the first time in many years. I had to re-buff a panel, which would have been a real problem if it wasn't in a place I work several times a week anyway.

So, I came up with a solution. I scrape the 1500 with the back side of a long knife I have to knock off the highest particles. You can feel a difference when you run your hand over the Trizact 1500 but there's no difference in the speed it cuts or how long it lasts, and buffing gets it done without any problems coming back.

Of course, I run the 3000 over the top too, just to make polishing easier, faster and safer.

Robert,

After your heads up I've discovered that the best way to fix the 1500 Trizact problem is simply running an 8" drywall taping knife over it while it's either sitting on a table or on the pad once or twice. This is a very uniform way of doiing this and seems to work great. Thanks for the heads up.

the dry 1500 is what needs to be knocked down right?

but Dennis and I are talking about the 1500 Trizact wet.
It can't hurt to do it to the 1500 FF.

You must understand how Trizact is made and why this problem is likely unique to it. This is done by embossing. Sort of like the special roller your mon had to make Christmas cookies. The reason Trizact has these uniform pyramid structures is because a precisely made roller imparts this pattern onto the wet abrasive slury during manufacture. It appears that some extra slurry features (point defects) might be left on the film after rolling and this is what the taping knife quickly removes.

Thank you for the input. I put the job on hold until Len gets the 1200 to me along with 1500 trizact. I really like the trizact and will try the drywall knife on it before I use the next disc.



Thanks
