3m acryl putty6/28
I just started working with this thinking it would dry faster and harder than the muralo spackle I usually use. It does dry fast and hard, but seems to shrink a lot. Anyone have the same experience? I have the white color, maybe the red or green behave differently?
this is a glazing putty. it is intended for very small defects (such as pits in bondo). It should be applied super thin to super small defects. Dont try to fill a nail head in with it or you will be disappointed.
Its desiged for pinholes in filler and primer. Its will fill relatively(based on ones's own experience) wide and deep scratches.
The Muralo Pro grade green can spackle is excellent for nail holes. Screw holes need body filler.
We don't really get pinholes or scratches. More of an auto/marine problem. Fiberglass composites primarily.
Sounds like you are using a 1K putty, a
Nitrostan, 3m glazing,acryl putty are for minor minor defects like pinholes. On a car when you throw on a coat of body filler it always has little air bubbles. Those need to be filled. On fibreglass boats there are likewise little air bubbles generally referred to as porosity. Then there are the typical little scratches that happen.
What finishing products are you currently using?
Thanks, everything seems to check out. This stuff is great for very small defects, but too much shrinkage for anything like nail hole. Iím using it with post cat primers and cvís.
It does not sand as well as the bondo one part red spot putty. I was hoping it would since a white color would be nice. I donít care for it.
If you are not liking the red color of the Bondo get yourself some white hardener.
We use the green 3m acryl after the first coat/guide coat of primer.... after this we primer prep and examine the piece and spot putty defects we missed in raw prep.... Obviously we use it for light cracks and small holes defects.... anything that has more defect we revert back to a bondo like material... the green really helps to know when it's filled and sanded correctly... then we hit it again with with a full round of primer coats to gain film thickness and re-prep for final topcoats... the spot putties are just that.. another tool in the box... use it were its correct and it's great.
