Mr. Surfacer

Mr Surfacer is a primer, IMO, one of the best out there.

Comes in either bottle or spray-can.

I have problems using it with an airbrush. Either it is too thick or vice versa. Anyone has advice what is the best ratio?

Thank you.

Your thinning ratio will depend on your airbrush(ie. nozzle diameter), thinner and air pressure too.

Sorry, no golden rule that will work guaranteed for everybody.

i suggest getting Mr. Surfacer in a spray can. i tried to clean the stuff up after spraying it and it was a total disaster. its like "mess" redefined. however, i use the Mr surfacer in a bottle to fill small seams, and it works like a dream.

Mr Surfacer can be cleaned up and thinned using Cellulose Thinners.

I use Humbrols gear, and it cleans up extremely well.

Check to see if your airbrush can handle the thinner, as this type has a tendency to eat rubber o rings, and if used raw on styrene it really turns it to goo.

Which is good if your making a liquid styrene gap filler.

Forgot to add, I wouldn't use it as a base coat for Alclad.

While Mr Surfacer is great for filling and priming, I personally don't feel comfortable using it as a base for NMF finishes.

Alclads Microfiller is all I'd use for my NMF's

Thanks for the reply.

I am using Mr Color thinner to thin Mr Surfacer and use the normal paint thinner to wash the airbrush. I have tried using Mr Surfacer from a spray can but I find it hard to control and normally ended up with a thick coat on the model.
