Glassfiber putty vs west systems resin/microballones

[lr172]

I used evercoat rage extreme on my 10. I have done a lot of auto painting and much prefer poly putties to epoxy. I did use 3M High strength repair filler for anything that needed rigidity or strength before the filler. I agree that epoxy based fillers have their place in some applications, but for smoothing an F/G top, poly fillers are much faster and easier to work with.

Don't use basic fillers for beefing up low areas near the door. build up with something stong, with filler on top to finish it off / clean it up.

Cabolsil makes resin thixotropic...it doesn't run. Cabo is not a filler material.

I've seen four or five different fillers applied to the same RV-10 cabin top. For sure, it is very difficult to sand a flat surface contour across fillers of different densities. Much better to contour using just one.

Primer-surfacers and high build primers are used later, with block sanding, to optically flatten prior to paint.

What exactly are you trying to do?

Thank you guys for the insights!

Dan, I installed the RV10 cabin top overhrad console, and now I wish to fill all the gaps, holes, smooth the surface ,round the cabin top pillars before primers and final paint.

I guess I will start with WS and balloons.
Final finish with putty? Or still with ballons?

Tnx

Hi Oren.

I did my cabin top interior with Epoxy/Micro mixture, faired it and then skim coated with straight epoxy. I then applied high build primer and painted It worked out very well.

Gaps, holes, and shaping around pillars are all jobs for micro.

This is honeycomb and glass, faired with micro, sealed with an epoxy skim, followed by wet-on-wet epoxy primer and PPG K36 high build. Nothing else needed. I restrict polyester to small defects discovered after the first coat of epoxy primer, if any.

There are no magic product shortcuts. Shape and surface are products of care and work.

+1 for Poly Fiber SuperFil! It sprays real nice if you dilute as per instructions. If you spray VS brush or roll, it will take very little sanding to get a nice smooth service.

Here's a pic of my finished top using Poly SuperFil. I was happy with results.

Perhaps you meant Poly Fiber Smooth Prime?

Super Fil is a two-part epoxy filler, basically expensive pre-mixed epoxy and microballoons

Yep! Thanks for catching that error! It is Poly Fiber Smooth Prime.

Ah. That makes a little more sense.
