I Just Bought A Project Boat. I've Been Poking Around Here For A Bit To Learn What I Can Of Gelcoating(there Is No Saving My Original Gel) I've Read It's Thicker Than Paint So I Assume My Hlv Gun Would Need Some Modifications (different Tip?) And I've Read Lots Of Sanding,is That Because Its So Thick It Goes On With A Way Bad Orange Peel? Doesn't It All Come White And You Have To Add The Color. I Have More Questions But I Better Stop Here For Now.
