#1 Rust Oleum Automotive 260510 12 Ounce Sandable

Rust Oleum Automotive 260510 12 Ounce Sandable Cover

I use it in 3D printing, and the effect is very good. It basically makes anything printed at 0. 2 mm disappear.At 0. 3 mm, you can still see the number of layers, so you still need to do some coats and a lot of polishing.

This thing is great on PLA printing, and 0. 1 mm is really unbeatable.

#3 3M 03584 Professional Rubberized Undercoating

Your old car primer is now super easy with 3M professionals. You can't lie. You don't know how people paint cars with 10 cans or less? I have 17 cans, and it may take another 60 miles to complete the fender. I primed my 1992 Mustang from bottom to axle.

I just bumped into everything and it looks beautiful. If you accidentally step on the gas, it will smell bad. Buy a cheap paint suit on the street and these things will sell badly.

#4 Seymour 20 1675 Professional Etching Through

Seymour 20 1675 Professional Etching Through Cover

If you're a weekend fighter doing a little manual work at a time, it's hard to grab your spray gun, go through the hassle of measuring / mixing primers, and then clean up the mess. I have tried several products from the "box" store, and they are all "rubbish". Many of them are not well sprayed, the sand is poor, and Seymour's professional primer is great.

It is laid correctly and beautifully built, and it is easy to sand as advertised. I wish I could try it earlier-it saves time.

#5 U POL 0741V Acid Primer Aerosol

U POL 0741V Acid Primer Aerosol Cover

It works very well. Use in a well-ventilated place, strictly follow the instructions, and the most important thing is to wear an acid gas mask with this product! Even a small amount can severely burn your sinuses. I know this because I smelled it when I took off my mask.

10 minutes after spraying.

#6 Dupli Color EFP101007 General Purpose Sandable

Dupli Color EFP101007 General Purpose Sandable Cover

I need some primer and it will have more "fill" to be used on its 3D printed plastic parts. My goal is to cover up "print lines" as much as possible, and based on some suggestions I found online, I tried Dupli-Color.

These results left a deep impression on me and surprised me. It works much better than I expected, and together with some other final steps, it has produced some 3D printer parts that you can't even tell. I know this is not the intended use of this primer, but I want to review it anyway because it works so well for me.

The jar is sprayed evenly without spots or water droplets. When used according to the instructions that should be dry, I will use this brand and product on future printers.

#7 VHT SP102 FlameProof Coating Black

People have made a lot of negative comments on this, but they are not sure why. If you follow the instructions, it will work. Sanding the rust / paint / chrome on the Harley container and tip with sandpaper. Wash with alcohol or brake cleaner.

I've never touched them with my bare hands. Be sure to wear gloves. Put on the primer first and then paint it. I am very careful with the watch on my Harley. I didn't follow the treatment schedule because a Harley couldn't be idle for 20 minutes without overheating.

Take a 2-minute break, take a 5-minute break, take a 10-minute break, and ride easily for 30 minutes. The pipe looks great!

#8 U Pol Raptor Etch Primer Aerosol

I have used this product before and it works very well. I find it inconvenient when I paint the jeep with a Raptor lining, but the old YJ looks better than the new one when it comes out. The paint of this Raptor is really stupid, professor, as long as you do it properly, clean and a little sand

#9 SEM 39683 Grey Etching Primer

SEM 39683 Grey Etching Primer Cover

I use this as a primer for an aluminum carriage. I first wash the aluminum with denatured alcohol, polish it, then clean it with denatured alcohol, then blow it off with compressed air, then apply three layers of SEM self-etching primer between the two layers at intervals of 5-10 minutes, then apply a layer of Rustolem professional primer, then apply a layer of Rustolem professional primer, then apply a layer of Rustolem professional primer, and then apply 3 layers of Rustolem self-etching primer between the two layers.

The time is 5-10 minutes. This is because SEM does not recommend applying the color directly to the self-etching primer. Finally, I put two layers of Valspar tractor / machine paint on it. Everything that is dry is very hard, and the paint has a very good adhesion to aluminum.

  • Description:SEM 39683 Grey Self Etching Primer - 15.5 oz.
  • Brand:SEM

#10 3M Primer Pint Wrapping Application

3M Primer Pint Wrapping Application Cover

This thing even has a strong grip on cheap vinyl rods. You can walk a long way with a little bit. I don't need a multi-layer coating, even on my four layers of plastic, because it's old and sun-damaged. This is a particularly good product close to the edge because it maintains the position of the edge and the position of the whole part.

I used a small paintbrush with a width of 4in. It wasted a lot of products because it was too thick. In my opinion, it works a little bit. I also brushed it with vinyl many times and found that it ensured that the edges were not wrapped and stuffed in place.
