whats the best over all clear to use for final clear coat over grafix dont want to use imron or auwgrip

i have used PPG's 2021 for years with great results, its a high end clear that lasts. Sands and buffs easy (if necessary) but get on it in the first day or two.

I do all my paint work with BASF dc5300 clear.

Can't go wrong with PPG 2021 or 2042 if they still make it, used it for years. Currently using Dupont 74500s. Great high solids clear also.

thanks for the input

PPG as above, or Matrix Systems

House if kolor urethane clear has great flow out and uv protection.

Can anyone tell me what clear holds up best for gas vapor and spillage around the gas tank vent? The type of clear used on my boat either turns brown or peels off and then grafix comes off next about a 3 to 4 inch area. Any cure for this?
