Product Spotlight

Tonight’s product spotlight, as last weeks, can be used to prep a surface to be repaired with adhesive, but also has many other uses in the field from medical prep, general cleaning of sticky substances like tree sap and even as a fire starter.

Alcohol Swabs
Available at pharmacies and grocery stores, I much prefer the felt type pad version on the left over the folded kind.

RTV Silicones
Always choose a non corrosive, high performance silicone. The right parts show the old school vinegar smelling silicone which is corrosive. All Major manufactures make both types .

Original hood foam Is injected to tie the thin door skin to the stronger frame. This foam usually delaminates quickly and causes the hood skin to “Flutter” while on the road at speed. I added a special anti-flutter that eliminated the issue.

The switch sleeve is badly cracked and chipped due to age and the heat of the compressor. I would suggest a hybrid adhesive like Loctite HY 4070 to keep the old part or use an epoxy putty to build a new one.
