Well, the 2K Rubberseal aerosol can testing continues. Today it’s the 2K filler primer part number RS-586. I have to say, I am really impressed by these products so far. I posted a while ago reporting the results of the 2K epoxy primer RS-587 finding it totally insoluble to lacquer thinner and urethane reducer. I did a very aggressive rub test and they didn’t even touch that epoxy primer.
This primer didn’t hold up as well to the thinner rub test. But it does take a pretty good rubbing to get a little color on the rag. It still held up darn good. It is an “iso-free” filler primer similar to PPG’s NCP primers and even smells like it when sanded.
The amazing thing was the filling and sanding qualities. I did a repair in polyester putty on a Toyota Camry fender. I finished off the filler in180 grit as I usually do. But I didn’t think that was enough of a challenge for that primer and half of the filler I finished blocking it with nice sharp 80 grit.
I applied it as per the instructions on the can with 5 coats with a flash of 3-5 minutes. Now, it was darn hot at about 90 degrees out so it flashed pretty fast. I added another coat over the area of the filler that was sanded with 80grit. I thought for sure that this little aerosol can wasn’t going to fill that 80 grit at all let alone with only 5 coats knowing how aerosol cans cover like crap.
Well, how about 1 coat made 1 mil! So at the 6 coats I had 6 mils! The one can covered this area with 5-6 coats no problem and I had a lot left so I made another test panel stripped to bare metal and just kept applying coats……13 of them. The can was still spraying good at 5 hours after busting the hardener container in the can. It did have kind of a “chunky” effect near the end. The first coats on the fender, that sucker sprayed like a little touch up gun, very nice with no splattering.
So, on this test panel, how about 15 mils!
I blocked the fender with 320 and then sanded it with 600 and then prepped the fender for a blend. The 6 coats filled those 80 grit scratches no sweat! I blocked and sanded very aggressively without sanding thru!
Coming up next….how about the paint being applied with a “Pre-val” aerosol system and then the RS-588 urethane clear aerosol can! Yep, I am doing this whole job in 2K products and no spray gun or compressor. I’ll report on that later.
