surface shield makes tar undercoating flake off ! !

surface shield makes tar undercoating flake off over night. it comes off in huge sheets. Fluid film was on there for a year, and the undercoating was intact.

surface shield is supposed to be better in the wheel wells because it is tougher

fluid film flows+recovers better so it is said to be better on the main chassis

[3D Model] Mud Flaps

I came across these mud flaps a while back of unknown origins and figured maybe others would enjoy them too. These are too large for my printers bed so you'll most likely either need to outsource the print or cut the model in your slicer of choice. More details can be found on my makerworld page linked below.

The STLs are located here: https://makerworld.com/en/models/277...a-fb-mud-flaps
NOTE: I haven't test printed these but I modeled them using a photo and measurements for scaling.

Thank you!

dash warning lights came on, car continued to work fine

suddenly all the dash warning lights came on, car continued to work fine. I noticed the + battery terminal has hair (oxidation). Removed the battery for charging from a battery charger, it looks like it was very low.
I remember replacing the alternator in 1994.
Is the external (from the alternator) voltage regulator the problem ?

Belt configuration after air pump and TR delete on SA models

Hey everyone,

I know this has been talked about before but with the closing of pineapple racing, the yoohoo belt seems harder to come by and purchasing a belt from NAPA seems to be very tedious.

I�m wondering if just gutting the air pump and leaving the pulley in place is the most reliable way to go?

Curious what everyone thinks
