Dykem Industrial Marker, Medium Tip, Black Color Family, Paint 44250-1 Each

worked perfectly; on my exhaust pipes

Works great

It unfortunately didn’t work great for the purpose I purchased for. No hard feelings, there’s always a chance some things don’t work out. I’m sure this product is great for other task.

Worked great on engine compartment bolts

Used on cleaned Diamond Cut Bare Aluminum Cylinder Fin Edges to Black the edges out. Long long time to dry ! Multiple Coats require even longer Dry Time. If you try to go over one coat b4 it Skins Over, it will just Lift The previous coat(s) right off ! Tried baking final coats it just reactivated it, it became Sticky & Would completely come off if touched. You Must Prime The Tip B4 Use=Press & Draw a Short Line on a clean piece of plastic, then Apply. Looks ok Not Glossy Not Flat Black, Wanted Flat Black, hopefully as time & heat cycles proceed The Acrylic Blk Paint Will loose its Shine. As to Durability on my Motorcycle's Cylinders, Only Time Will Tell. So far I Recommend It. Be Advised, There is a Definite Learning Curve* as Stated in My Review.

After priming the paint pen, it flowed smoothly onto the surface of my fusing glass project. Recommended.

Ease of use. Painted lettering on valve covers.

Bought this to touch up some minor dings I made while assembling my new Weber ELX smoker. Easy to touch up and holds up to the heat generated. But, once dried, it does not match the shiny color of the porcelain finish on the smoker. Still works well to cover the dings.
