There's a guy at work who does restorations and custom painting who told me about a product by this name. He said you spray it in hard to get to/hard to sand areas like door jambs to soften up the existing paint so you can spray over it with your new finish. He says to use this instead of trying to get into those areas with sandpaper. He claims it promotes bonding between the factory paint and the new paint that's about to sprayed. Has anyone heard of this product?

Jamb it,Midcoat adhesion promotor and the stuff your talking about all are designed to do just that,promote adhesion.I wouldnt totally skip the sandiing and rely on that.You should sand it the best you can,try a red scotchbrite pad for hard to sand areas like jambs and then if you want a little insurance you can use that stuff but its not a replacement for proper sanding.

AHHHHHMen/ on that. Hows that old saying go ? If it sounds to good to be true .
The old snake oil or in this case ,
Door jam prep in a airasol can.
I have seen the aftermath of Jam-It after a trip to the local car wash.
As he said Randy. after scotch red and final clean. in the imposible place to reach areas.

Nothing takes the place of elbow grease I suppose. Thanks guys!
