Easy to install a must have for rust proofing
The plugs fit snug and are water tight. Make sure to also buy the drill bit for these.
These are a must have for rust proofing & buying the bit & the plugs together is the best way to go.
With this I was able to apply Fluid Film into the insides of the doors and lower rockers giving my car awesome rust protection. Applied in the heat of August to give the film time to settle into all the crevices. With these plugs in place next year it will go much faster. I highly recommend this product.
