I have a few questions about silicone. instead of red rtv silicone can i use blue rtv silicone? Also can I take it out if I screw up or if it wears out? And will it wreck my yoyo if I screw up putting in the silicone?
Silicone is like rubber. Blue silicone is same as red silicone. Just take a needle and stab it and pull gently, even a baby could take it out. And no silcione wont ruin your yoyo, (unless you put it in the axle seat or bearing sit.) But if you do get some there clean it, silicone somewhat cures in 8 hours in like 4 it begins to get its rubbery. And make sure you have a small enough tip because silicone is heck of a job to get off. I just tape all of my yoyo before I silicone and only leave the groove open.
