Yeah its pretty crazy how far water based paints are getting. My buddys father owns a pretty reputable custom car paint shop and and asked what it was he was using. Assuming to hear some new lacquer or enamel....when he said he switched everything over to water based and occasional alcohol in airbrush work. I was absolutely blown away that water was capable. And was half the price and far less likely to die from fumes lol.

I've never used the polish sanding trick but then again, I buff with 3 compounds not 2. Funny how we all do the same things but just a little bit different. I like that because it helps me to explore better/different techniques. Always looking to improve! Thanks Chris.

[@davidbarselow7848]

I think your method would be removing more than desired material during the buffing stage, Unless you apply the necessary amount to make-up the difference, which cuts (no pun intended) into the bottom line during tax season.

[@johnklimeck]

Thanks Chris, excellent as usual. 800 seems too highly to start, even 600, but, I had to do 320 to remove pad marks… which is why I am switching to spraying now. And if one is spraying, there will be no marks so 800 would work… I suppose 320, 400, 600, 800. Another thing I noticed, Sandpaper manufacturer is important. My black sandpaper clogs and can be disastrous. My 3M 216U is so easy to clean. I am officially never going to use anything but 3M 216U now…

Keep it up. i build guitars as a hobby and i wanted to ask is car polishing compounds (cause compounds for epoxy are pretty rare to find over here) a viableway to buff a finish?

[@mariapanagi3391]

There are so important what you teach us. Thank you so much!!!! Is it possible to have this shiny result without using water or machine?

[@ryanstark2350]

You need at minimum 2000 grit if you are going to buff without a dedicated machine. I use wet and dry for sanding but you need to make sure water does not get into the wood meaning all parts need to temporarily sealed. For example any scew holes otherwise the wood will expand in those areas and then contract when it dries which will slightly warp your totally flat fimish.

[@GIBKEL]

Got any tips for a cerused finish? The ash was grain filled but despite sealer, fill, sealer, and 13 light coats of nitro, you can still feel the grain. I imagine it is a delicate wet sand. It has a fairly shiny finish with very little orange peel except for the maple neck. As it stands, I may just start with 600 and work my way to 12 or 1500 then put it through some heat and a freezer to check the finish- then a final buffing.

[@onpsxmember]

Excellent video. Those are very helpful. Do you sand the edges directly, or do you leave a thin line until the buffer? If you do sand the edges, do you go over the edge in your quarter or do you go along the whole edge? I'm really scared of those edges.

[@CodyGleason]

Thanks for the recommendation for the Super Assilex. I've been looking for a replacement for the 3M flexible sanding sheets since they discontinued them, and this looks like it may be similar. I live and die by those sanding sheets.

[@HighlineGuitars]

According to the 3M website, Flexible Hookit 270J has not been discontinued. Only the trial pack was discontinued. The individual sheets are still available.

[@templetonpeck393]

I think I would personally mask off the sharper edges with fine line tape or thin masking tape. The lacquers sit lighter on those areas and I wouldn't want to burn through to the base. But that's just what I'd do.

Love your videos. I’m in the middle of finishing a Chinese knock off kit and it looks like I may have level sanded through a couple of places on the edges. I used Keda dye and Solarez. Looks great but I think I may need a few more coats of Solarez. My question is, how do I fix the spots where there appears to be no more dye? Any help would be greatly appreciated.

[@murpsman]

How do you keep from sanding the edge when you sand the sides? I invariably burn the edges when I sand like that.

[@TomL-]

Great video! I have a fair amount of experience with painting, sanding, and buffing in an automotive application, and I know that edges are particularly scary in that you have to pay close attention to the direction of the rotation in relation to an edge so that you don't buff the paint off of the edge. I've never used a buffing wheel, or buffed a guitar....or water based for that matter.....is it just as critical and delicate near the edges using the buffing wheel? And how easy is it for the guitar to get ripped out of your hands when doing the horns? Thanks!

[@HighlineGuitars]

The wheels are too soft and spin to slow to burn through at the edges unless you really try. In the dozen or so years, I've used buffing machines like the one in this video, I have never had a guitar body or neck ripped out of my hands.

[@fjb5894]

Looks good from far away but needed a closeup shot just one time?

[@pmcm-ih1ep]

I have a buddy that paints cars and uses some real nice Iwata spray guns. His finishes are so nice they don’t even need wetsanding and he goes straight to buffing. They literally have practically zero orange peel. My goal is to get at least half as good as him so I can just wetsand with 1500 grit and go straight to buffing.

[@daveg4236]

Been a year... How are you coming along with that goal?

[@Fazman81]

Hoogla Boogla sometimes I get a really flat finish and can just do 1500 and then 2000. Sometimes I get a little dust nib or not so flat and have to start with 1000.

[@thezogs95]

Does this work for a drumset? I have vintage tama superstars with a laqure finish. I was hoping to buff them like this even though the drums are of course...round

Question: About how long should I allow the finish to cure after its application before beginning this process?

[@danwhitehurst9592]

[@jimpeters9748]

Thanks for the tips. What materials did you use to wipe the surface clean of the medium buffing compound? Solvents?

[@HighlineGuitars]

No solvents are necessary since the compounds leave a dry powder. All you need is a clean soft cloth or paper towel.

[@stevenfolino405]

Thank You Chris, very informative and helpful. I’m using quality automotive urethane paint products and a StewMac buffing machine and I have what looks like very fine scratches under my Tamco clear. I use mineral spirts instead of water and I am very careful to not cross the different buffing wheels. I’m going to try your suggestion of less grits, maybe 800, 1,000, 1,500 then the two buffing wheels of medium and fine. ANY suggestions would be greatly appreciated. Thank You very much for the video.

[@HighlineGuitars]

When you apply the clear, are you sanding between coats? Scratches left by scuff sanding can migrate up through the finish and be revealed when level sanding. Also, scratches can occur due to contamination.

[@stevenfolino405]

@@HighlineGuitars Hey Chris, Happy Halloween. Thanks for your response. First, I do not sand between the clear coats. I shoot the base coat, wait the regulated time and then shoot the clear. I built a small 6’x6’ spray booth in my garage so it’s relatively a clean spraying environment. I use mineral spirts to wet sand with and I’m thinking maybe it was contaminated. I’m curious about the dry sandpaper you used. You showed that it doesn’t load up, and you wiped it occasionally. Do you recommend I try it? Your body came out great looking. Id like to get those kinds of results. Which dry paper do you prefer most? Again, thank you Chris for your time and advice.

[@Ray_Here]

Thank you for your instructive videos. I have access to a buffer but the polishing compound may be a few years old. Does it go bad. It’s from a company called Menzerna out of Germany.

[@trumpetRex]

What about refinishing an older instrument rather than a newly painted one? Is there any surface sealer you have to use over the old finish (trying to preserve some of the original patina) in order to promote adhesion of the final layers? Over shellac, lacquer, or maybe a finish that contains oil based stain? thank you!

Hi, I asked you this last week but I don’t know if you saw the comment. What do you think about using Solarez as an initial base layer/sealer/grain filler and then over coating that with the crystal lac instrument finish?

Yes, it would work.

Hello Chris. If I may ask. What rmp would you recommend for compounding and also polishing on a hand held polisher? I have a Avid dual action random orbital polisher that the slowest rpm is 2700. Is that to fast or aggressive for a polishing speed?

[@HighlineGuitars]

Sorry, I don’t know. I have never used a hand held electric polisher. I am considering switching from my big buffer to a hand held polisher, but I need to find one that can run from zero rpm and up. That way I could test to find the optimal speeds.

Very informative video. I have a fender American original '60s Stratocaster that has some waviness going on in the finish or body, I don't know which, but I am starting to wonder after watching your video if sanding it down and then buffing it could make it flatter and not have all the crazy wavy reflections going on. It is a lacquer nitrocellulose finish. Do you think that is an option?

[@HighlineGuitars]

I doubt the clear coat is thick enough to sand it level.

[@j_music_8779]

I've been doing finishes for a long time. I've always wet sanded in a circular motion however several KZbin lessons say sanding in one direction is better. I tried this on a recent finish and I'm not sure it looked any better than finishes I sanded circular. Is there any science behind either method being better?

[@HighlineGuitars]

In my videos, I use both motions depending on the desired outcome. For speed, I use a circular motion and for the final grits, I use one direction (usually with the grain) which reduces undesirable scratches.

Hi! First of all your videos are great and very inspiring! I've a question: I'm on a satin finish on my very first build right now and I necessarily need to level sand. Which is the target sandpaper grit I should reach? I don't need to buff, i guess, as I want a satin look, but I neither want a 'scratched' surface, which is the result of 1500 sanding. My target is a satin, but flat, surface. Should I buff and then use 0000 steel wool to bring back the satin effect? Or simply reach an higher grit when level sanding? I really hope for your help, I'll take you advices as the Holy Bible. Thank you!

What is the best method for removing surface scratches ie. marks in the finish of a guitar? Can you buff them out? I have a Yamaha classical acoustic guitar that I bought as a second and it has some marks in the lacquer that are visible when looking across the surface.

[@HighlineGuitars]

A lot depends on the type of finish that was used on your guitar and how deep the scratches are. If the finish is a lacquer such as nitrocellulose, you could try rubbing out the scratches with a clean cloth and some rubbing compound (Meguiar's M110 Mirror Glaze) followed by another clean cloth and some polishing compound (Meguiar's M210 Mirror Glaze). Finish with a third clean cloth and some swirl remover (Meguiar's M9 Mirror Glaze Swirl Remover). If that doesn't do the trick, you may have to lightly wet sand the area(s) with some P2000 grit wet/dry sandpaper wrapped around a small rubber sanding block. Then, proceed with the rubbing compound/polishing compound/swirl remover as described. Hope this helps.
