Is this normal amount of black specks/debris on reprep for three wheels?

Thanks!

I ran the same cotton swab through the bore of the one extra wheel, polished the same way that did not race, and there was no debris. What in the world goes on in there to create such a mess? By the way finished with the red rocket and ran oil.
 
I'm assuming that you re-polished the wheel bores. I am curious though, did you use compressed air to blow out the bore before waxing?

*new builder warning regarding the advice below *

Sometime ago, I have tried to save wheels by re-polishing the bores when dish detergent and water failed to get me back to the times I thought I should be running. It has never worked out. Honestly, now, if I consider re-polishing a wheel in an attempt to save it, it will become my NDFW or trash. I only polish a wheel bore once.

On a re-prep, I may either clean the bore out with water only (some use car wash) and re-wax, or use dish detergent and a pipe cleaner to strip the wax before re-waxing. But, I have never seen that on a re-prep.
 
That is not normal unless you're polishing. If you're not polishing something you used may have eaten the wheel bore. The propellants in Jig will do this if you haven't properly coated the wheelbore and or used the Jig to quick. I don't know your process. Check the bores with a loupe to see if they're damaged.

I think that you may have nailed it Kinser! I took a new wheel and ran my cotton swap through the bore and it was clean. I sprayed my silicone substitute on the wheel and waited 15-20 minutes and ran my same cotton swab through and it was black.

I thought my silicone was safe on the wheel and so used my micro brush to coat the inside with it (I did not do this on my spare wheel), thinking what do I have to loose? I guess a lot. I did get some jig. Thanks Rocket car! I was going to test and see if it was better then mine. I guess it is back to the drawing board and will need some new wheels soon and retest both sprays. I sprayed mine on the wheel and didn't see any damage, I thought it was more like the Blue spray. I guess I was not looking close enough.

I only hand spin my wheel's on the cotton swab. Using it in a drill seems to take the gloss out of the wheel bore. I don't even like to use the cotton swab, even hand spinning. I have other polishing compounds I use with the fluffy pipe cleaner only. I used the cotton swab's on these "reprep" wheels as I used my micro brushes just to brush the inside and they were so dirty I went to the cotton swab and was dismayed.

Thank you very much for the wisdom in where to find the source of the problem!

I know one of the 50% that eat plastic. I will keep it a secret for now.
 
This forum is for sharing. Remember when your friend used to act all excited and say " I've got something to tell you!" and then after you get hyped up and ready for the new information, and then your friend replies, " Never mind, it's no big deal." All you can think about is what it could have been. Well, ah, never mind I'll leave it at that you probably didn't want to here it anyway.

I put some jig on a spare wheel to see what would happen. It was VERY BAD. It is nothing like this other silicone spray I put on the wheel. I cleaned up the black specks and looked in the bore under magnification. It doesn't look bad at all. I am going to Red Rocket them again and try them out.

I don't think that you want any speed secrets from me Bulldog. My kids were dead last in their open oil divisions at MA.

Note to self though: I may want to try and apply the spray or oil to a dummy wheel first before using it on good wheels and seeing if it eats the wheel checking with some sort of cotton swab. Again, I thought that I did do this, I guess not well enough.

This is not faster than Jig.

The company makes a lot of other ones you could try.

Re-prepped the wheels with 2 coats of Red Rocket and used Jig on the axles and was able to gain some speed

. It doesn't look like the wheels were toast.

Thanks!

I saw a graphited penetrating oil, anyone ever try it?

I have the graphite spry Dryphite It is nice. It dries fast. It didn't help much when we were running graphite. But that was before this site and and all of the improvements that come with it.

I do/have put it on the DFW inner outermost edge that a will ride the rail. I did not when we last tested the car (yesterday) and they were faster then before, but that was do to the Jig I am guessing. That is about the only modification that we may do before the race. Do people feel it is worthwhile to add graphite to the surface that will contact the rail on the DFW? No need to burnish with dryphite. Easy to apply accurately with the microbrush.
 
I pulled a wheel off of the car after the council race and ran a brush in the bore and it was clean. No black specks after this race. Now I know what not to do and will need new wheels for next year. We must have been running with imperfect bores.
