Solvent adhesives... why don't more people use them?

.. shouldn't you already know all this stuff?

What were to happen if you used both ABS and PP shavings to create your adhesive goop, since Acetone will dissolve both ABS and PP?

You'd think... but all I deal with is methanol. I asked my boss because he knows all about that plastic stuff. He's the one who told me about the acetone/PP solution and where to find pp to grind up.

just a quick report from the home depot. The one closest to my house does not carry ABS pipe or the oatey abs pipe adhesive. So apparently that is not a reliable source. still looking.

Wow, that's weird. I managed to find a 2 doller 2 foot pipe at home depot no prob, but couldn't find Oateys, so I ran over to Lowes (just on the other side of the street lol) and found Oateys there in the plumbing/piping area. Originally I was looking in the paint/bondo area but in both stores it didn't exist in that section.

yeah oateys is definitely a plumbing thing

This is actually what I was thinking... make youself a hybrid plastic goop and I bet you'd be set... not sure of a source for PP though... maybe you could do a little experiment... mix up some ABS goop and then find a nice, hidden spot on the back side of a dash panel (marked PP) and smear a small glob on... let it cure and then see how it holds. On the subject of seeing how it holds, I remember doing an experiement with Sintra (poly vinyl material)... we stuck a couple pieces of Sintra together with the Sintra goop (mixed with THF as the solvent)... we let it sit for a bit and then tried breaking it apart... the joint held and one of the pieces of Sintra broke! DOH! Kinda backs up my point of it never cracking out like FG (fiberglass) and bondo...

Anyway... below is a picture after 15-20 minutes of sanding... I knocked some high spots down and have a couple small voids to fill... rather than go the "icing" route, I'm gonna fill it one more time with my ABS goop and sand one more time. I think after that sanding, I should be able to prime and paint. It sands real nice leaving a nice, smooth surface just like the sanded OEM ABS.

I'll post more pics later...

When you are spraying, look for "Plastic bumper" primer. It allows you to use any normal rattle can paint on almost any type of hard plastic, instead of having to make special precautions with mixing primers and paints prior to application with a gun.

When you apply it, it is clear and dries to a very translucent, almost transparent pearl, stick 2 coats of that, 3 coats of normal primer and whatever top coat you want to use (gloss/Satin/matt/texture etc). The paint sticks perfectly and doesn't peel in the slightest.

Thanks for the info on primer and paint... I HATE painting... I absolutely SUCK at it! lol I have actually planned to have another installer friend of mine do the paint as I don't want to screw it up! lmao Anyway, maybe I'll give it a shot... its been ages since I've even tried. I'll do more sanding tonight... then I'll have to go in search of paint supplies. I'll post more pics as they come.
