Hello
I use quite a bit of Permagloss in my rod work.
I find that the key to success is thin coats and a faster RPM when turning the rod.
Because the material cures up so fast if the rod is rotating slow it tends bunch up or glump.
Another problem is the shelf life A partly used bottle has a tendency for the unused material to change in viscosity and get thicker.
As per the Manufacturers instruction I put the partly used bottle in a sealed plastic container and keep it in the refrigerator this really extends the shelf life and also keeps the original viscosity of th material.
The other thing I do is I only put small amounts of material in a cup at at time enough for 3 or 4 wraps.
After I have applied the material to say 4 wraps I clean my brush and get another clean cup add enough for 4 more wraps and so on.
When the material gets to the point that it starts to loose it's original viscosity (thicken) I thin the amount I am going to use in a cup with a eye dropper a drop or 2 of acetone at a time until I have the viscosity I want.
When going over old wraps and finishes I scuff them up with either scotch bright or in some cases fine sand paper.
This is very important or the new finish may lift later.
Another thing I almost forgot to mention is the need to inspect the material for floaters.
Often the material will develop a ring of hardened material at the neck of the bottle .
When removing the ring be very carful not to allow any of the hardened material to drop in the bottle even the smallest flakes will cause clumps if applied to your rod.
When I pour the material from the bottle I clean ID of the neck and inside of the cap with a dust free rag or Q Tip swab.
This helps to keep the hardened material from forming at the neck of the bottle.
If I do have floaters as I like to call them and I only do this when I absolutely need too I pour the material through a coffee filter to remove the floaters.
Most times though I just toss the bottle and start a new one.
The other thing I do is I only purchase the small bottles this aids in the loss of material as I find most times I end up tossing a good amount of the larger bottle because of shelf life issues or floaters.
With the smaller bottle I have better luck and less hassles.
I hope I have been some help.
