I already have the "tools" Makita buffer (used it to strip paint) and just bought a 3/32 sander.


I am now looking to pick up the materials from Len that I will need to color sand and buff my 69 Mach I which I hope to have sprayed before Christmas. I will be using PPG base/clear and going with the original Lime Gold Metallic, which is a very light green/slightly gold metallic.

I have the hook it pad and interface pad for the D/A... just need to pick up some finishing film, wool and foam pads and the Sure Finish from Len.

This will be my first time using finishing film. Was thinking 1500 finishing film dry, followed by 3000 trizact wet before moving on to polishing. I am using the Plus gun and just finished an overall on my daughters car with very little orange peel, so was thinking of starting with the 1500 instead of something more aggressive. I am happy with her car as it is sprayed, finish looks as good as new cars or better.

Can the Trizact 1500 also be used dry, in place of the finishing film? Then move on to the Trizact 3000 wet? If it cannot be used dry (1500) than I will just use the finishing film, as I like the idea of the "dry guidecoat" since I am a newbie at machine sanding clear.

I looked at the Sure Finish kit and was thinking about just getting a wool pad and the orange pad instead of the whole kit. What is the difference between the two 7.5 inch wool pads (high density, loose) do I need one or both and when would it be appropriate to use each?

Should I just suck it up and pony up for the whole Sure finish Kit :+confused

Let me talk about the Trizact Clear Coat Sanding Discs for a minute. Donít be afraid to use something wet. That seems to be the secret to there long life. There are no pig tails when using them wet. Youíll get pig tails with finish film in just a minute or two, and then you will need to clean the disc with a towel or your pants leg if you arenít too worried about damaging your pants. You can do that twice then replace the disc, or keep using a warn out disc and muck up your finish. The secret to using the Trizact disc is to have a squeegee and pull off the water to look at the surface.

I went to an auto parts store and got one of those window cleaners like they have at the gas station and use it to wipe the area I am sanding. I just let it lay on the car near where I am working. As soon as the rubber removes the water you can see how it is coming. No need to be completely dry. You will see shiny spots where there is clear coat that hasnít been hit by the disc yet to tell you that you need to keep sanding. After you have checked 3 of 4 times you will have a good feel of how itís going and you can check less often. You will spend more time changing finish film discs than you will spend squeezing water to check progress.

You're right Bob, a Trizact 1500 disk can wet sand an entire panel and then the 3000 disk can do several panels. The down side for a novice is that they can't see what they are doing while they are doing it but with a little practice it's not that hard to master. One of the reasons we recommend Finishing Film is that it can be used dry and the dust acts like a guide coat showing you where you stand during the sanding process. But I'm with you, we sand with Trizact almost exclusively. I use a 3" squeegee to wipe off the water when I need to look at the surface.

As far as the Sure Finish goes we use the 6" backing plate (G), the orange pad (A) and the black pad (B) and a quart of Sure Finish is usually plenty to do an entire car after sanding with 3000 grit Trizact. If you want to start your polishing by removing the scratches a little faster you can begin your buffing with the 6" wool pad (D) then move onto the foam pads.

Thanks for the info guys... I am getting very little peel, mostly just want to get the nibs and get a nice finish.


I think that I will pick up the Trizact in 1500 and 3000, using both wet and also pick up a squeegee to check my work. I definitely don't want to deal with any pigtails, if they can be avoided.




Sounds like one quart of Sure finish should do at least one car. I will pick up the 6 inch backing plate, wool pad and orange pad. Had read that the black pad was for dark paints (which I will not be using) should I also pick up the black pad?




How many Trizact pads for an overall? I will be sanding everything without the exception of the hood which will be blacked out (black base with PPG 2060 flat clear).

Maybe 5-6 of the 1500 Trizact and 2 of the 3000?

Yes you can use the black foam pad to work on swirl marks and any product left. I think a Very IMPORTANT item when you're done is a goo microfiber cloth. You will be AMAZED at what it does to make the gloss deeper. Really picks up any film looking residue.

For taking off of wet sanding goo when using Trizact a California Water Blade works really well.
