Tamco Monocoat is great

This penetrating paint goes a long way. Whatever you are painting make sure your piece is above 60 degrees. It loves warm metal. I used a heat gun to get my metal up to temp. It is Winter and my basement is around 55 degrees. Im painting suspension parts on my 2000 Mustang GT. I already started spraying topcoat on some of the parts and they look great. Great product.

Great undercarriage paint

The Monocoat went on perfect, I reduced it 15 percent and sprayed my frame and under body. After 24 hours you can’t dig your fingernail into it. Tough paint for sure

Covered more than I planned!

I bought a can. Planned a few parts and one inside fender engine well. Ended up doing both inner fenders, right front quarter if frame, control arms and under the hood as well as half the fire wall. Still had 1/4 of a can left. Can run pretty easy. Video says put it on thick. I did and got some runs. But as it's a bottom coat I'm not worried about them much.

Excellent frame/suspension coating

Stuff went on glossy, but drys to a "satin sheen" I would say. Ended up looking perfect for an undercarriage. This stuff sticks better then any other product I've tried. I brushed on which came out great with only minor brush strokes in some places. After drying for 3 days I performed other repairs which had me spraying brake clean, and other caustic stuff on frame and scrubbing hard with a rag and this stuff didnt budge or look any different. This will be my go to product from here on out. Note: garage was 90 degrees and within 15 minutes it was practically dry or had consistancy of almost cured 2 part epoxy glue.
Thanks for this product.
