the 3m 5200 is what we used on my tail wheel skid it cures in about 12-24 hours if there is enough humidity. In AZ I had to drape wet towels over it. it is very sturdy an a little flexible. Best stuff I have ever used and it is white

3M 5200, available in 7 day cure or 24 hr cure in the boating section of Academy outdoor and Sports
Good luck!!
