Hi all, I just finished a Hawk Howard "IKE" kit. My first 1 day kit! Unfortunialy due to age, the decal backs had yellowed,not good on a white surface. I thought I read on the forem that you could put them in the sun to bleach them. Can you re-print them on clear decal paper without a yellow tint? Any pointers would be appericated. Thanks much AARDVARK
