Paint film cracked around sharp edges (e.g. masking tape edge, joint or groove where body and guard meet). At times, the film may ‘tighten’ across an acute angle and separate from the substrate without cracking.
a) Insufficient sanding around joints, mouldings etc. resulting in lack of adhesion.
b) Too heavy a build up of material on these areas.
a) Detailed sanding around suspect areas.
b) Eliminate heavy build up of material around sharp edges, corners and mouldings.
If bridging has occurred, remove finish from affected area, detail sand and refinish, spraying thinner coats and leaving extended drying time between coats.
